The adaptability and reusability of SDRadar have expanded their application in many healthcare applications. An SDRadar is usually designed with a basic architecture that includes a transmitter, receiver, and a digital signal processor. The transmitter sends out radio waves, which are reflected, or penetrated and scattered, from the targeted object. Those reflected or scattered signals are captured by the received and processed using a digital signal processor to extract useful information. This flexibility allows SDRadar to be easily reprogrammed for different tasks without changing the hardware. To support and motivate researchers and practitioners of various scientific and engineering expertise, a state-of-the-art review of SDRadar, focusing on the healthcare applications of continuous waves, frequency-modulated continuous waves, and stepped-frequency continuous-wave modes, is presented. The review focuses on heart rate and respiration monitoring, as well as medical radar imaging, over a broad frequency range from 0.2 GHz to 20 GHz. Future research trends and potential advancements are also discussed.","PeriodicalId":29955,"journal":{"name":"IEEE Journal of Electromagnetics RF and Microwaves in Medicine and Biology","volume":"9 3","pages":"253-262"},"PeriodicalIF":3.2,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144896817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is essential to quickly and effectively disinfect the air to prevent the spread of pathogens, enhance public health, and guarantee health and safety. Electromagnetic disinfection is a new type of disinfection technology, which has been proven to inactivate various bacteria, viruses, and other microorganisms, and has the advantages of high efficiency and environmental protection. This study proposed an electromagnetic disinfection-based method for microbial aerosol disinfection. Electromagnetic field theory was used to establish the cavity's starting size, and electromagnetic simulation software was used to model and simulate the cavity. Then, a cavity system was established and disinfection experiments were conducted on indoor air and high-concentration microbial aerosols. The results show that when sterilizing indoor natural air, using an electromagnetic field with a frequency of 2450 MHz and a power of 200 W for 70 seconds can kill 93% of the bacteria in the air. In high-concentration aerosol disinfection experiments, the disinfection effect can be significantly improved as the power and action time increases. Most microorganisms can be removed when the electromagnetic field power is 200 W and the action time is 2 minutes. These results indicate that electromagnetic disinfection devices can effectively eliminate microorganisms in aerosols and provide a new method for controlling disease epidemics.","PeriodicalId":29955,"journal":{"name":"IEEE Journal of Electromagnetics RF and Microwaves in Medicine and Biology","volume":"9 3","pages":"368-376"},"PeriodicalIF":3.2,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144896844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Depending on the tumour depth, it is named superficial or deep HT. This study focuses on superficial hyperthermia, evaluating critical aspects of quality assurance (QA) procedures to understand their implications for treatment effectiveness. QA protocols involve temperature measurements in non-perfused tissue equivalent phantoms to assess HT device performances. An analytical formulation of the transient bioheat transfer equation, supported by numerical and experimental results, examines the electromagnetic-thermal phenomenon in perfused and non-perfused tissues, analysing stability, heating-up times, and thermal response evolution. Results show that the absence of blood perfusion significantly influences the transient thermal behaviour and temperature distribution, with time-dependent effects. A numerical study explores the temperature distributions induced by an electromagnetic source in a multilayered phantom replicating the QA setup. The influence of dielectric and thermal properties of the materials making the phantom on the QA parameters, such as temperature rise (TR), thermal effective field size (TEFS), and thermal effective penetration depth (TEPD), is assessed. Simulations reveal the impact of thermal properties on temperature profiles, highlighting the importance of designing phantoms with properties representative of real tissues.","PeriodicalId":29955,"journal":{"name":"IEEE Journal of Electromagnetics RF and Microwaves in Medicine and Biology","volume":"9 4","pages":"408-416"},"PeriodicalIF":3.2,"publicationDate":"2025-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145560758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A combination of such sensing features is in demand for monitoring of organ-on-chip systems; however available sensing technologies have yet to address this need. In this work, we explore the possibility of leveraging the inherent features of dielectric spectroscopy for the application in organ-on-chip systems, by investigating three key technological developments using open-ended coaxial probes. Firstly, biocompatible non-contact sensing capabilities are proved by showing similar sensing performance of Parylene C-coated probes and uncoated probes. Secondly, a setup and methodology are developed for highly accurate and non-destructive height positioning of the probe to allow for precise extraction of intermediate sample layers. Finally, non-contact multi-layer sensing performance of the presented technology is successfully demonstrated by means of a biological phantom in a three-layered system. With further integration, dielectric spectroscopy can potentially become a cornerstone sensing technique for organ-on-chip by enabling real-time non-contact tracking of various tissue contents and properties.","PeriodicalId":29955,"journal":{"name":"IEEE Journal of Electromagnetics RF and Microwaves in Medicine and Biology","volume":"9 3","pages":"360-367"},"PeriodicalIF":3.2,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144904888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work is one of the first demonstrations of simultaneous concentration extraction of three liquid constituents in a solution using broadband microwave spectroscopic data. Furthermore, the used methods eliminate the need for de-embedding or characterizing the measurement setup, simplifying the process. Advanced regression techniques such as Principal Component Regression (PCR) and Principal Least Squares (PLS) are applied to determine the concentrations of sodium chloride, glucose, and ethanol in water. As input data, <inline-formula><tex-math>$S$</tex-math></inline-formula>-parameters are measured between 0.5 and 26.5 GHz on a broadband coplanar waveguide sensor with a microfluidic container to transport the liquids. The training datasets consist of 27 and 34 samples, respectively.

MaRCoS (MAgnetic Resonance COntrol System) is such an open-source system that has been well-tested on various low-field systems. However, due to limitations of the basic hardware, MaRCoS is constrained in its ability to support a wide range of field strengths and RF (radio-frequency) channels. In this study, we aim to port the MaRCoS console to high-field (up to 125 MHz Larmor frequency) MRI systems and increase the number of RF receive channels, enabling phased-array coils and/or active EMI (electromagnetic interference) elimination techniques. A series of implementations were conducted across 0.11-, 0.5-, and 1.5-Tesla MRI systems, to evaluate its compatibility and performance. Promising results indicate that the extended console not only matches but, to some extent, surpasses the performance of a commercial console, particularly in terms of flexibility and accessibility. It is hoped that this study could effectively expand the scope of open-source MRI technology, making MRI scans more accessible and affordable.","PeriodicalId":29955,"journal":{"name":"IEEE Journal of Electromagnetics RF and Microwaves in Medicine and Biology","volume":"9 3","pages":"351-359"},"PeriodicalIF":3.2,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144904635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
