In previous work, the metamaterial patterns on the lens layers were produced using an etching approach on commercially available dielectric copper-clad substrates. In this paper, the meta-lens consists of metamaterial square-rings that are inkjet-printed on ultra-thin dielectric layers of polyethylene terephthalate (PET) using silver nanoparticle ink. The metamaterial square-ring units of variable sizes are distributed on the thin dielectric layers to satisfy the required refractive index distribution. Simulation results of a 12 cm lens operating at 13.4 GHz demonstrate the collimating features of the proposed lens.","PeriodicalId":180982,"journal":{"name":"2021 United States National Committee of URSI National Radio Science Meeting (USNC-URSI NRSM)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125904323","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}

Electromagnetically transparent coating materials can be a very good candidate for addressing such an issue. 2-Dimensional hexagonal Boron Nitride is a newer material gaining a significant attention for its structural similarity with graphene and corrosion resistive functionality without being electrically conductive, unlike graphene.

Typically, restrictions on the maximum permissible field level for a device to cause over a certain frequency range are imposed, based on characterizing the device's radiations in the far-field. We present a probabilistic approach to characterize and model radiated interference, based on stochastic electromagnetic fields. This allows for computationally predicting the probability for exceeding the emission threshold, set by international electromagnetic compatibility regulations.","PeriodicalId":180982,"journal":{"name":"2021 United States National Committee of URSI National Radio Science Meeting (USNC-URSI NRSM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129683174","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 wide bandwidth was achieved by exciting the patch antenna with four proximity coupled feeds from a wideband phase shifting network.

The peak gain of the antenna was simulated to be 4.4 dBi at 2000 MHz in the broadside direction. This was achieved while maintaining a very low profile of 0.05λ, where λ is the wavelength corresponding to the lowest operating frequency.

Most previous studies do not consider the effect of body temperature on the antenna's performance, though tissue dielectric properties are temperature-dependent, and typical human tissue temperature is between 32 °C to 37 °C. In this study, we used the ANSYS HFSS and ANSYS Icepak simulation tool to study the effect of tissue temperature on the performance of a set of antennas placed on the skin layer and implanted inside the muscle tissue. The antennas were designed to work around 1.3 GHz for an ambient temperature of 25 °C.
