Due to BP anisotropy, for polarization in the armchair or zigzag directions, we have a single operating band, and for a 45◦ polarization, a double operating band. The dynamic control of the proposed structure can be performed by varying the electronic doping in the BP, thus changing the operating frequency of the filter. The analytical model based on the Temporal Coupled-Mode Theory is in a good agreement with the numerical simulations by COMSOL Multiphysics.","PeriodicalId":124570,"journal":{"name":"2021 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128885567","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}

This operating characteristic was achieved by inserting smoothly in the corners of the ground plane. The structure operation electromagnetic characteristics were calculated from the numerical techniques for full-wave analysis of the Finite Integration Technique (FIT) and Finite Elements Method (FEM), and showed that the proposed antenna is capable of covering the 22.8 – 25.4 GHz band for the first band, the 27.4 – 30.7 GHz band for the second band, and the 37.8 – 40.3 GHz band for the third band. The high and low cut-off frequencies for controlling the device’s operating bands were set at the cutoff threshold at -10 dB for return loss. The results calculated by FIT and FEM show good agreement, validating the study presented.","PeriodicalId":124570,"journal":{"name":"2021 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126674653","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}

However, such sources are still a technological challenge. One option is to use weak coherent states to mimic single-photon pulses or to produce a pair of photons with parametric down conversion and to detect one of them to herald the presence of the other. In this direction, the present work shows how to produce better approximations of single-photon pulses by using a nonlinear phase modulator in a Mach-Zehnder interferometer.

In this work, an organic-inorganic hybrid is presented as a PUF token to be utilized in optical authentication of cryptographic systems. Using a Discrete Cosine Transform (DCT) analysis applied to the speckle patterns produced by the PUF token, a low-cost and semi-compact 128-bit key encryption optical system was implemented.
