As exemplified herein, physically-motivated equivalent circuit models can be setup to scale accurately with part-value, substrate properties and other parameters, such as solder pad dimensions. While powerful and enabling, these globally scalable circuit models cannot generally account for electromagnetic coupling interactions between components and between components and their surroundings. Consequently, full-wave Electromagnetic (EM) analysis has become a crucial step for radio frequency (RF) design in order to account for interactions between components and between components and their shielding and interconnect environment. However, such models often require access to proprietary component composition details. A solution to these challenges is described in the form of IP-encrypted 3D model libraries. These libraries use technology recently available in some EM simulators, for encrypting geometry and material details to protect vendor manufacturing IP. This advance enables 3D EM models to be shared with a wider design community, helping designers reduce design risk and re-work and improve time-to-market for today’s increasingly compact and complex product form factors.","PeriodicalId":276613,"journal":{"name":"2019 IEEE International Conference on Microwaves, Antennas, Communications and Electronic Systems (COMCAS)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123495511","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}

Such interference is random and highly dependent on the employed transmission technique, as well as the varying channel conditions and the varying association between users and base stations. Traditional networks at lower frequencies usually employ omnidirectional transmission which creates an (almost) equal amount of interference in any direction. MmWave networks, however, must employ directional beamforming transmission in order to compensate for the high path loss in mmWave frequency bands. These directional transmissions drastically change the network interference structure. We examine the interference power distributions in an mmWave network employing beamforming transmission under different user association schemes, and contrast with those under omnidirectional transmission. Numerical results using an analytical mmWave channel model and a measurement-based channel generator, NYUSIM, show that beamforming not only reduces the amount of strong interference and hence significantly enhances network throughput, but also user association can considerably alter network interference and throughput structures.","PeriodicalId":276613,"journal":{"name":"2019 IEEE International Conference on Microwaves, Antennas, Communications and Electronic Systems (COMCAS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129251991","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}

Remcom’s WaveFarer® is a simulation tool that combines ray-tracing algorithms with high-frequency asymptotic physics methods, with Physical Optics (PO) and the Method of Equivalent Currents (MEC) at its core, supplemented by Geometric Optics (GO) and the Uniform Theory of Diffraction (UTD) to handle multipath interactions between structures. In this paper, WaveFarer is used to evaluate radar returns from vehicles in a typical road environment. Drive scenarios are then constructed with the radar and vehicles in motion, along with stationary roadside clutter. Simulation results are post-processed to calculate additional quantities, such as the range-Doppler. The objective of the study is to demonstrate the ability of simulations to characterize radar scattering from vehicles and features along a road, at ranges and frequencies relevant for automotive radar.","PeriodicalId":276613,"journal":{"name":"2019 IEEE International Conference on Microwaves, Antennas, Communications and Electronic Systems (COMCAS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122217338","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}
