The improved algorithm uses a good-point set combined with opposition-based learning to initialize the particle swarm. Three parameters are also designed to balance the influence of inertial weight, personal experience, and social experience. Furthermore, to prevent falling into local optimal solution, twenty percent of particles with the worst fitness are disturbed based on the logistic chaotic equation in each iteration. At the same time, the algorithm uniformly quantizes the amplitude and phase of the element to satisfy the hardware requirements. Simulation verifies that the proposed method can simultaneously generate multiple beams with almost the same gain regardless of the size of the array, so it could be a good choice for communication systems and microwave imaging.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"39 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":"128427897","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 development of THz antenna is mainly limited by the difficulty in micro-size fabricating and low efficiency caused by non-negligible dielectric and metal losses. This work proposes a structure of PCB-based stripline series-fed slot antenna array for THz high integrity application. To limit energy spreading, standing wave resonating cavity is built by surrounding each transmission channel with metallized vias based on through glass vias (TGV) process. The slots cut the current on the surface of the resonating cavity, thereby generating radiation. A 94GHz slot array prototype is designed and tested, fed by a WR10 interface, with the help of a dumbbell-shaped coupling slot etched on the ground, who functions as a waveguide-stripline transition structure. A metal base and a protective lid are also designed to facilitate testing. The simulation results of this prototype show that the antenna has an efficiency of 78.2%, a gain of 10.7 dB, and a bandwidth of 1.8% (93 GHz ∼94.7 GHz) with |S11| < −10 dB. Due to the dielectric constant and machining error, the measured resonant frequency deviates from the simulated one 3%. Based on this structure, highly integrated sub-terahertz (sub-THz) or THz array with high gain and low loss can be implemented and applied in imaging systems.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"15 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":"129145452","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}

On the basis of a wide literature analysis, and after building up a solid knowledge repository, we were able to build up an Artificial Neural Network (ANN) so to predict the impact of the treatment in terms of ablation area. In this paper, we demonstrate that the same approach can be extended so to allow the optimum choice and tuning of some parameters with an important impact on the quality of the treatment, such as the position of the electrodes, their size, geometry, etc. This allows the customization of the treatment to a wider variety of diseases, and its tailoring on specific cases or patients. We finally propose the extension of the ANN approach to a novel application area, extremely important in many biomedical applications: gesture recognition. We demonstrate that the approach, combined with the use of a special glove using chipless RF tags, can be effective in the detection of the movements of fingers in a human hand. For this application, we also investigate some open problems and future developments.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"22 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":"125652566","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}

Then, based on this transform, the estimation of LFM signal frequency modulation slope, initial frequency and amplitude are realized.

It was observed that the structure of Interstitium closely resembled Jī ng Luò in Traditional Chinese Medicine (TCM). As TCM has not been recognized as a science in spite of its 47-century history, we latched TCM onto Interstitium, then distilling and synthesizing TCM to conform to modern sciences, thus raised TCM to an experimental science. We then formulated a theory of Chee for this experimental science, resulting in a Scientific TCM (STCM). Biomedical applications for STCM and the theory of Chee are discussed. It is expected that the research is leading to new scientific discoveries as well as new diagnostic and therapeutic instrumentation and procedures—with robotic and even supernatural potential—from the vast inheritance of TCM accumulated since 2700 BC.","PeriodicalId":305829,"journal":{"name":"2022 IEEE MTT-S International Microwave Biomedical Conference (IMBioC)","volume":"13 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":"126319495","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}
