Demystifying Material Parameters for Terahertz Electromagnetic Simulation
نویسندگان
چکیده
Two industry-standard electromagnetic modelling software packages, HFSSTM and CST Microwave Studio, are used extensively for modelling arbitrary THz structures. However, with both there are a number of practical issues that relate to how such commercially-available software can be used to give results that are meaningful and accurate. In this paper conventional air-filled metal-pipe rectangular waveguides have been simulated, using a raft of different approaches, with a view to illustrating weaknesses in accuracy in a quantifiable way. This paper highlights a number of incorrect approaches, some being intuitive and logical, and makes recommendations for the most appropriate solutions.
