To enhance the gain, a metasurface lens and| U-shaped slot are loaded on the Vivaldi antenna, which increases the forward gain. The antenna properties have a contribution to improving the detection capability of the respiration radar ranging from 14 to 16 GHz. The simulation and measurement have been performed to evaluate its characteristics and its performance in supporting respiration radar operation. As a proof of concept, a prototype is designed, fabricated, and tested. A good agreement is observed between measurement and simulation results. It achieves an impedance bandwidth from 11.5 to 21.3 GHz (59.76% FBW) for a −10-dB reflection coefficient with port isolation higher than 24.92 dB. The realized gain is up to 10.5 dBi, the radiation efficiency is 88.01-90.02%, and the envelope correlation coefficient (ECC) is less than 0.00122 among antenna elements. Integrated with the designed and fabricated transceiver based on the 65 nm CMOS processing, the test circuit and system are built up. The experiment is conducted by using the respiration radar. The extracted phase information from the raw data shows that the proposed wideband antenna sensor can be used to identify the reflected signal from the chest wall at inhaling and exhaling phase of respiration activity.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115326459","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}

However, even in the case of IMD, due to the limitation of battery life, it is necessary to replace the battery through a short cycle and reoperation. Research is being conducted to apply wireless power transfer (WPT) technology to the IMD to reduce the reoperation cycle and reduce the battery size. Due to IMD being inserted into the human body, there are many considerations to apply WPT. In this paper, the basic principle of WPT and design conditions for the WPT system for IMD are explained. We subsequently provide a review and survey of research on WPT systems for IMD.

The scale transform-orthogonal chirp division multiplexing (ST-OCDM) signal has become a promising candidate for JRC systems due to its orthogonal chirps with adjustable chirp rate that provide higher flexibility than traditional JRC signals. However, ST-OCDM based JRC signal suffers from the high peak-to-average power ratio (PAPR) problem. This paper introduces several peak clipping methods to solve this problem. The comparison of simulation shows that the multiple scaling signal to clipping noise ratio (MS-SCR) CR technology has the best peak clipping performance.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130299108","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}

However, depending on the ratio of the penetration depth and the curvature radius, this may lead to a non-correct estimation of the power absorbed by the tissues due to constructive/destructive interference. In this study, we propose an accurate evaluation of the area-average absorbed power density in curved tissue-equivalent models by computing the surface integral of the normal component of the absorbed power density vector field. The numerical analysis is performed for plane wave exposure of an ear model at 60 GHz. We also investigate the effect of the averaging area shape on the absorbed power density by considering 1 cm2 square- and disk-shaped averaging surfaces. Results show a substantial relative difference of 14 % in the area-averaged absorbed power density over a disk-shaped averaging surface between transverse electric and magnetic polarization, with the reference being the value of the area-averaged absorbed power density for a planar homogeneous model and normal incidence. By using the same reference value, negligible differences of 1.81 % and 0.92 % for transverse electric and magnetic polarization, respectively, are present when the averaging area shape changes. According to the studied exposure scenarios, the area-averaged absorbed power density variations as a function of the averaging surface geometry are less significant than those related to the polarization of the incident field.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117222953","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}

These devices rely on knowledge of skin dielectric parameters. Skin thickness varies with body location, and, hence, the goal of our work is to characterize the dielectric skin properties in the microwave range as a function of skin thickness. To do so systematically, and in a controlled laboratory environment, we developed skin phantoms models ranging from 0.5 mm to 5 mm in thickness, with 0.5 mm increments. These phantoms are placed on a fat-mimicking material and then characterized with the Keysight slim form probe over the 0.5–2.6 GHz range. Our results indicate that skin thickness, usually known from extensive anatomical resources, should be taken into account for proper interpretation of eventual dielectric characterization in vivo, as the probe's sensing volume is likely to include a complex, multi-tissue dielectric distribution.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126012223","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}

The rationale is that the piezoelectric film can cause changes to the incident mmWave signals due to the piezoelectric effect when sound waves hit the film. Moreover, we find that the mmWave signals can penetrate common soundproofing materials, which pave the way for through-obstacle speech recovery. Based on this, we propose a new mechanism to decode the phase-demodulated audio signals from the reflected mmWave signals. To combat the penetrating and propagation loss of mmWave signals, we further developed a speech enhancement method based on the deep neural network. The network can filter the raw recovered speech and reconstruct clean speech with higher speech quality and intelligibility. We evaluate the proposed system on a public dataset. The results indicate that the system can recover high-quality and intelligible speech from a distance of 5m in the case of occlusion.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122195701","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}

Thermoacoustic signals are easily interfered by factors such as temperature and mixed with incoherent noise during propagation, both CEEMD and SVD have a good effect in extracting the main components of the signal and removing noise. The main idea of this method is denoising artifacts by decomposing the ultrasound signal received by the sensor into a series of intrinsic mode functions (IMFs), choosing the effective IMFs based on SVD. We tested a single tumor in the homogeneous media by numerical simulation. The peak signal-to-noise ratios of the thermoacoustic images reconstructed by the proposed method, and the other three methods are compared. The results indicate that the method of CEEMD combined with SVD has better performance.
