The filter is a two-stage band-pass filter fabricated with double-side Au film and the central frequency is 220GHz. The electromagnetic modeling, simulation and analysis of the bandpass filter are presented. The influence of the dimension of the Jerusalem cross cell on the transmission characteristics of the band-pass filter is discussed. By optimizing the dimension of the Jerusalem cross cell, the band-pass filter shows that the insertion loss is −1.9dB∼ −1.6dB with a 3dB bandwidth of 8GHz, and the return loss is less than −8.9dB.","PeriodicalId":297368,"journal":{"name":"2018 12th International Symposium on Antennas, Propagation and EM Theory (ISAPE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115513777","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}

By collecting the observing data onboard CSES including electric field, in-situ plasma parameters and energetic particle flux, the results show that in local daytime no pumping waves were detected by the electric field detector (EFD) on CSES even the emitted power reaching 90 MW, and no any obvious plasma disturbances were observed from CSES. While in local nighttime, the pumping waves were clearly distinguished in HF-band electric field at the emitted frequency with the emitted power only 30MW, in which the power spectrum density of electric field was larger than the normal background to an order of magnitude, with the propagating radius exceeding 200 km. This joint experiment of SURA-CSES illustrates that, CSES can cross SURA facility within a quite near distance with present designed orbit, which can insure the effective heating time from SURA and make CSES most possibly to observe the perturbations at the topside ionosphere excited by SURA.","PeriodicalId":297368,"journal":{"name":"2018 12th International Symposium on Antennas, Propagation and EM Theory (ISAPE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128443275","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 this parallel FEM-DDM, the domain decomposition is done in a hierarchical way to minimize the inter-processor communication. In the hierarchical domain decomposition scheme, the whole FEM solution domain is first decomposed into large size subdomains with a total number equals to MPI processes. Then, each large subdomain is distributed to a MPI process and further decomposed into smaller ones to achieve good computation efficiency. Numerical examples are presented to demonstrate the accuracy, scalability, and capability of the proposed parallel FEM-DDM algorithm.","PeriodicalId":297368,"journal":{"name":"2018 12th International Symposium on Antennas, Propagation and EM Theory (ISAPE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128277924","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 order to better exert its value, there is an urgent need for a high-power ultra wide band antenna to effectively radiate electromagnetic energy. In this paper, the CST microwave studio is used to simulate the electromagnetic Vibrator Combined antenna to determine the size and shape of a single antenna. Then simulate the $3times 3$ array antenna. By changing the antenna spacing, it is found that: 1. The beam width in the horizontal plane is only related to the spacing of the antennas in the horizontal direction; 2. The beam width in the vertical plane is only related to the spacing of the antennas in the vertical direction; 3. The gain of the antenna fluctuates with the change of the antenna spacing, and remains basically stable at $lambda/4simlambda/2$.","PeriodicalId":297368,"journal":{"name":"2018 12th International Symposium on Antennas, Propagation and EM Theory (ISAPE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128958788","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 reflection terahertz wave intensity from the prism-air-vanadium dioxide-metal interface is controlled by via changing external temperature. By adjusting the external temperature, the refractive index of vanadium dioxide can be changed, so that the terahertz wave reflectivity according to geometrical optics reflection is dynamically controlled. The numerical results further show that the present structure can flexibly manipulate terahertz wave transmission. The extinction ratio is about 20.18dB in our design, which has enormous potential for studying terahertz wave manipulation.","PeriodicalId":297368,"journal":{"name":"2018 12th International Symposium on Antennas, Propagation and EM Theory (ISAPE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126873570","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}
