It is usually modeled by tetrahedron or hexahedron, but there is a limitation in using one mesh alone. When using a tetrahedron, there are too many unknowns. If a hexahedron is used, the fitting performance to the target is poor. This paper proposes a hybrid grid modeling DGTD algorithm, which divides the computational domain into tetrahedral subdomains and hexahedral subdomains, and sets the swap boundary transfer information at the intersection of different subdomains. Numerical results verify the feasibility of the method.","PeriodicalId":254491,"journal":{"name":"2019 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference (CSQRWC)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121841852","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}

It is validated using the 0.18-μm standard BCD(BiCMOS/CMOS/DMOS) process and is used for electrostatic discharge (ESD) protection of RF communications. The HBM level of the device is estimated based on the results of the transmission line pulse test. The human body model (HBM) of the PGDDSCR device is 4.5 KV, the breakdown voltage and the failure current are 21.1 V and 3 A, respectively. Due to the short-circuiting of the polysilicon gate of the anode (cathode), the PGDDSCR device generates an electric field effect to promote the positive feedback effect of the SCR, achieving the level of protection required by the target system. And because the area of the ESD device is small, the parasitic capacitance present does not affect the signal integrity of the RF communication system.","PeriodicalId":254491,"journal":{"name":"2019 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference (CSQRWC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133739572","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}

At the same time, the energy transmitted by the power divider is coupled through two probes along the strip-line on the DRA sidewall. In addition, by introducing four vertical metal plates around the DR, the frequency range of Axial ratio (AR) is expanded further.

In this paper, by assuming that the instantaneous channel state information (CSI) is unknown at the source and relays, we propose a Q-learning (QL) based on relay se-lection method, which can select the relays with maximum cumulative reward to obtain the maximum throughput of the cooperative networks. Besides, Boltzmann learning rule is adopted to achieve well counterpoise between action exploration and exploitation. Simulation results show that the proposed QL algorithm can select the optimal relay adaptively and improve the system performance significantly in comparison with random selection algorithm. Furthermore, it can be found that as the number of relay nodes increases, the QL algorithm can still adaptively select the optimal relay without increasing the computational load.","PeriodicalId":254491,"journal":{"name":"2019 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference (CSQRWC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116903491","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}
