Although finite-state Markov chain (FSMC) has been extensively investigated, most of the literature about FSMC modeling only considered channel fading in the time domain or frequency domain. Only few FSMC channel models describing channel fading in both the time and frequency domains lack the support of measurement data. In this paper, we propose an FSMC model in both time and frequency domain for vehicular channels based on real measurements. We validate the accuracy of steady state probability (SSP) of the proposed model via real measurement data. And we also discuss the influence of different subband partitions and the size of the modeling region on multi-subband interval change probability (MICP). The conclusion of this paper can be used in future FSMC modeling for the non-stationary wideband channel.","PeriodicalId":6801,"journal":{"name":"2021 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (APS/URSI)","volume":"11 1","pages":"663-664"},"PeriodicalIF":0.0,"publicationDate":"2021-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89661053","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 metasurface had 25 complementary split ring resonators (CSRR) and was placed in the radiating far-field of the patch antenna. The conformal metasurface was printed with flexible NinjaFlex (substrate) and Electrifi (conductors) filaments, and the phase shift of the radiated field was achieved by changing the curvature of the conformal metasurface. The proposed system was simulated in HFSS. Furthermore, a prototype was measured, and the results validated the simulation results. The radiation pattern was shown to shift by up to 20 degrees in response to the curved metasurface. This proposed approach could eventually be used to achieve beam steering by combining a conventional patch antenna and 3D-printed metasurfaces.","PeriodicalId":6801,"journal":{"name":"2021 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (APS/URSI)","volume":"33 1","pages":"1441-1442"},"PeriodicalIF":0.0,"publicationDate":"2021-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89706198","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}

Period patch and grid arrays are designed to achieve different artificial impedance surfaces. Equivalent impedance boundary conditions are extracted based on simulated dispersion curves of unit cells. Simplified uniform waveguide models based on impedance boundaries are established to further investigate robust transport of interface waves along various routes. Due to the protection from duality symmetry, the interface waves are tightly bounded at the center of the waveguide. The proposed waveguide may pave an important research direction in wireless components design.","PeriodicalId":6801,"journal":{"name":"2021 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (APS/URSI)","volume":"6 1","pages":"1978-1979"},"PeriodicalIF":0.0,"publicationDate":"2021-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75452039","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 utilizing CMA to synthesize omnidirectional radiation pattern of the absorber's unit-atom under full PEC condition, the developed absorber can then convert the omnidirectional radiation pattern into near-omnidirectional absorption pattern based on dissipation tailoring. The developed absorber is three-dimensional, and its top layer is patch-type with broadband and angle-stable absorption within small incident angles. And the middle part is a lossy pillar to provide broadband absorption at large incident angles. The simulated results demonstrate that, in the frequency range of 1.2-3.0 GHz, corresponding to the FBW of 85.7%, the absorption of TE-polarized wave is over 90 % when the incident angle is less than 40°.
