That makes the broadband characteristic of the circulator. The structure is optimized in HFSS for better performance. From 4.5 GHz to 13.5 GHz, a strong circulation effect is observed and this proves that the nonreciprocal transmission characteristics are achieved skillfully. The circulator shows good nonreciprocal transmission characteristics. Moreover, the use of confinement electromagnetic waves can decrease the size of the ferrite and show a broadband characteristic.","PeriodicalId":132755,"journal":{"name":"2016 IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123049781","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}

Four rectangular ceramic blocks, which possess high permittivity and low dielectric loss, can be spliced together to make the designed shapes.

The band-stop response can be determined by the permittivity of the dielectric material, the periodicity and geometrical shape of the dielectric unit cell. The simulation results show that the FSS can achieve a stop band in 6.97-8.85GHz.

We use a metal corrugation for the former and parallel metal plates for the latter, both reasonable for the THz regime. Further, we extend the beamforming concept using LWA to mimic arbitrary diffraction optics and demonstrate focusing and Bessel beamforming.

A method for the bandwidth-control of terahertz low-scattering metasurfaces 一种太赫兹低散射超表面的带宽控制方法

This metasurface is composed of three kinds of units with different geometries, leading to various reflection phases as well as slight losses under the incidence of terahertz plane waves, thus inducing the destructive interference on the incoming waves. We take account of the losses in the design of the low-scattering metasurface, which is inevitable in terahertz frequency band and makes our model more accurately. Different from the previously published works, our design is manipulated over a broad spectrum instead of at single/center frequency, which is helpful to dominate the working bandwidth as desire. An optimization method is adopt to optimize the array pattern of the metasurface to attain the overall low-scattering feature. Simulation results show that the bandwidth of the metasurface is from 0.61 THz to 1.20 THz with the suppression ratio more than 8/9, which is in agreement with our prediction.","PeriodicalId":132755,"journal":{"name":"2016 IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131065209","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}
