This method combines ADI-FDTD, FDTD, transmission line equation, Kirchhoff's law, and two-port equivalent circuit model to realize the transient responses of a transmission line network. This hybrid method is carried out by dividing into two parts that one is ADI-FDTD for small structure and the other is FDTD for large structure of the transmission line network. With the unconditional stability, the ADI-solver can use the same time step with the FDTD solver even with different space cell sizes. Further, the voltage and current responses at the terminal of a transmission line network are calculated by using the hybrid FDTD method. The simulation results are in good agreement with the HSPICE method, which verifies the accuracy of the proposed method. This method can reduce the number of simulation iterations and improve the simulation efficiency without sacrificing accuracy.","PeriodicalId":254491,"journal":{"name":"2019 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference (CSQRWC)","volume":"10 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":"125284869","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}

When the incident angle changes from 0° to 60°, the absorption is more than 90% in the range of 8.2-25GHz , except for two dips at 21.2GHz and 22.5GHz with the angles of 45° and 60°, respectively.

At the same time of infrared radiation measurement, the meteorological parameters such as wind speed, wind direction, temperature and humidity were recorded. Based on the measurement data of October 1, 2018, the characteristics of ocean infrared radiation are statistically analyzed, which is consistent with the actual situation.

In order to fabricate the proposed slot array by computerized numerical control (CNC) milling technology, the length of metallic pins is selected as large as possible. Since the full-corporate feed networks are very dense, and only one row of metallic pins is required to isolate the coupling effect between any two neighbored distribution networks. In the work, height value of the bed nails are well selected so that the mutual coupling are below -20 dB. The simulated results show that the proposed array antenna has an input impedance bandwidth of 11% better than -10 dB. The bandwidth covers 135-150 GHz frequency band.

We consider optimal relay selection scheme based on network fairness in the system, an \"incentive\" counter is attached to every node, nodes compete to be relays through games to guarantee the fairness in the system. The relay with lower channel gains can be selected, then the selected relay will switch between full-duplex(FD) and half-duplex(HD) relaying which can operate on amplify-and-forward(AF) or decode-and-forward(DF) mode to get a higher channel capacity. The hybrid relay selection algorithm, NFHDAF, adopts the advantage of HD and FD, switching between DF or AF mode to get a lower outage probability. Finally, the numerical simulations show that the NFHDAF algorithm improves the performance of the system.","PeriodicalId":254491,"journal":{"name":"2019 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference (CSQRWC)","volume":"49 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":"128320417","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}
