The structure and parameters of hardware-in-the-loop (HIL) simulators, which is based on basic digital radio frequency memory (DRFM) technology are considered. Some possibilities of improving the FPGA implementation are suggested. One of the feature is the simultaneous realizing of a continuously variable delay and Doppler frequency shift by using a double-frequency synchronization of the input and output parts of the simulator. It is possible to change all main parameters of the simulation, including automatic adjustment to the modulation parameters of a radio signal. The proposed simulator is useful to perform a HIL simulation with finer verification of both receiver-transmitting microwave paths and signal processing algorithms of typical and cognitive communication and radar systems.","PeriodicalId":158616,"journal":{"name":"2019 Radiation and Scattering of Electromagnetic Waves (RSEMW)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132669875","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 rigorous mathematical models are based on the solution of the Maxwell`s equations with electrodynamic boundary conditions simultaneously with a model of the graphene surface conductivity determined from the Kubo formula. The mathematical modeling involves three specific methods. The reflection, transmittance coefficients and losses of periodic 2D arrays of graphene ribbon elements based on multilayered substrates, depending on the frequency and angle of incidence for different geometry and values of the chemical potential were calculated in the THz frequency range. The results show that the performances of graphene nanoribbon arrays THz absorbers, tuned by the external bias electric field, can also be controlled by modifying the 2D array geometry and areal density, through changing the periodicity, the size and the configuration of the graphene ribbon elements.","PeriodicalId":158616,"journal":{"name":"2019 Radiation and Scattering of Electromagnetic Waves (RSEMW)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124460910","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}
