The element is designed for operation at 4.1 and 6.6 GHz. By loading short pins, the proposed design exhibits considerable improvement in terms of the gain at higher resonant frequency, cross-polarization level, and impedance bandwidth, compared to the original design. Each design has been fabricated and experimented.","PeriodicalId":171472,"journal":{"name":"2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128999348","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 current VR device provides the virtual 3D images, but cannot synchronously detect the user's eye movements which could be significant for deriving the users' gaze points and interest regions in varied applications. In this paper, we proposed a smart eye tracking system for VR device. Firstly, a smart eye movement detection kit is mounted inside the VR device to capture the human eye movement images with the rate of 30 Hz. Based on the proposed eye detection kit, a gaze detection algorithm is then established for VR devices. Next, a gaze estimation model is proposed for human gaze estimation. The proposed smart eye tracking system can detect the user's eye movements in real time under VR stimulation. Moreover, it also provide a new human-VR interaction mode.","PeriodicalId":171472,"journal":{"name":"2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114204245","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}

Series feed antenna array is proposed to achieve high gain. Feeding network is elaborately designed in order to satisfy the radiation pattern and polarization requirements of on-body mode and off-body mode in WBAN. Series feed antenna array and feeding network are then integrated together to form the dual-mode multi-polarization wearable antenna. The wearable antenna can operate at on-body mode and off-body mode by exciting different ports. When the wearable antenna operates at on-body mode, it has omnidirectional radiation pattern with vertical polarization (VP). Additionally, broadside radiation pattern with left hand circularly polarization (LHCP) and right hand circularly polarization (RHCP) can be generated when it works at off-body mode. Simulated bandwidth is 2.68GHz with reflection coefficients lower than −10dB. Additionally, bandwidth of axial ratio lower than 3dB exceeds 4GHz. Maximum simulation gain of on-body mode and off-body mode is 2.1dBi and 5.3dBic, respectively.","PeriodicalId":171472,"journal":{"name":"2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125844077","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}

We conducted a computation evaluation of the transmitted power density and the local temperature elevation on the surface of a glycerine phantom with a dielectric property close to a human skin tissue. The measured near-field distributions of several typical antennas were used in the FDTD simulation. The analytical results indicate that the transmitted power density averaged over an area smaller than 4 cm2 is needed to correlate with the local peak temperature elevation at 60 GHz. This finding is valuable for discussing how to use the transmitted power density as metric to evaluate the beam exposure at millimeter wave frequencies.","PeriodicalId":171472,"journal":{"name":"2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131340455","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}

An example with two channel and each channel of two single-mode $(TE_{101})$ is demonstrated using substrate integrated waveguide technology. The footprint of the diplexer is reduced compared to the traditional ones since the cavity acts as a T-junction between the input port and the two channels and provides one pole for each channel filters. Furthermore, the fractional bandwidths (FBWs) of the two channel filters can be allocated flexibly based on the FBW design graph. A prototype centered at 11.6GHz and 13.6GHz with respective FBWs of 3.1% and 3.04% is designed for demonstration.","PeriodicalId":171472,"journal":{"name":"2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130729798","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 permeability of BBB was examined by using Evans Blue (EB) and lanthanum nitrate as vascular tracers. It was found that EMP reversely increased the permeability of BBB. Next, we explored the feasibility of EMP facilitating the chemotherapeutics to penetrate BBB and the treatment efficacy in a glioma-bearing rat model by detecting the drug (CCNU) concentration in tumor tissue, tumor size and tumor apoptosis. It was found that EMP enhanced the delivery of CCNU to tumor tissue, facilitated CCNU-induced tumor apoptosis, and obviously inhibited tumor growth.
