The sensor has single-layer structure and fed with microstrips and coupling branches. The quarter-mode design can produce resonance corresponding to the full-mode case while reducing the size and the amount of liquid. By introducing additional capacitance in the vertical direction, the folded structure enhances the slow wave effect and further reduces the size of the resonator. A PDMS chip with a microfluidic channel is placed above the resonator. The injection of liquid sample would cause frequency deviation, so as to retrieve the liquid property. The sensor is also expected to be used in the field of blood glucose monitoring and wearable devices.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"423 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":"133732198","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 reflection phase of a single EBG cell is investigated under various conductor layer sheet resistances. After meshing the conductor layers of the EBG structure, the variation of the zero-reflection phase frequency point as well as the bandwidth of the EBG cell is revealed. For planar monopole antennas, the optimized transparent EBG structure is employed to minimise backward radiation. The proposed antenna covers the 2.4 GHz industrial scientific medical (ISM) band. The antenna's high gain and low backward radiation in the operational band are confirmed by full-wave simulation. The EBG structure not only reduces backward radiation, but it also protects the human body by preventing the monopole antenna from radiating electromagnetic waves into body tissues, as well as minimizing frequency detuning induced by the human body. To ensure robustness and light transmittance, the proposed antenna was constructed on a transparent and flexible PDMS substrate. The proposed antenna's specific absorption rate (SAR) assessment showed that it is likely to be integrated into wearable devices for a variety of applications, especially in biomedical technology.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"19 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":"115472264","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}

In this study, we investigated the general characteristics of human exposure to plane waves at frequencies from 0.1 to 1 THz using several multilayer planar models of the skin.

This paper proposes a planar array of split-ring resonators (SRRs) over a dielectric substrate to study its performance for having a highly sensitive, non-label, and low-cost biosensor. By coupling the two SRRs of each unit cell, a pick in the transmission spectra occurs at 1.58 THz. Analyzing the electromagnetic field distribution and surface current flow shows the appearance of coupled electric and magnetic dipoles in the resonators. It is also shown that changing the distance between the coupled SRRs can passively tune the resonance frequency. Finally, the sensing functionality of the metamaterial is validated by simulating a human skin tissue with a refractive index of 1.6 and a thin thickness of $6 mumathrm{m}$.
