The FFT-PVVA solution is a hybrid of the FFT-accelerated field propagator between parallel apertures and the ray-tracing technique for the reflector reflection. Besides the high computational efficiency, the FFT-PVVA solution has the ability to accurately model near field diffraction, which is the key property of the CATR reflected fields in the quiet zone. The procedures in modeling the CATR by FFT-PVVA are demonstrated in this work, especially the efficiency considerations for modeling the electrically large reflector. The electrical size of the modeled reflector ranges from $367lambdatimes 367lambda$ (0.1THz) to $1467lambda times 1467 lambda$ (0.4THz), and the near-field results in the quiet zone are presented to validate the application.","PeriodicalId":247909,"journal":{"name":"2019 International Applied Computational Electromagnetics Society Symposium - China (ACES)","volume":"68 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120972393","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 each iteration of BICGSTAB, multiple global MPI communication collectives are required, which are becoming increasingly expensive when many processors are used on modern computers, especially on a large-scale system. To address this limitation, a communication-avoiding variant of BICGSTAB (CA-BICGSTAB) is realized and implemented to minimize global communication therefore improve massively parallel efficiency of the FEM-DDM in this paper.

The radiator occupies a tiny size of $15times 12 text{mm}^{2}$ and is suitable for the popular ultra-thin smartphone applications. By using T-shaped defected ground structure (DGS), a good isolation performance over 12 dB across the whole operating bands has been achieved.

The cavity filter was designed at the frequency range of 10.7GHz∼12.75GHz. Its lower stopband (9.85 GHz∼10.35 GHz) attenuation reach −40dB and its upper stopband (13.75 GHz∼14.5 GHz) attenuation can reach - 50 dB. High stopband suppression requirement can be obtained through introducing the transmission zero. Moreover, we use the tuning screws to achieve the miniaturization of the filter. The actual test results show that filter performance is obtained with insertion loss (S21) of 1dB and the return loss (S11) of −17dB.
