Abstract: When compared to the over-simplified classical skin-effect model, the accurate classical relaxation-effect modelling approach for THz structures at room temperature can be mathematically cumbersome and not insightful. This paper briefly introduces various interrelated electrical engineering concepts as tools for characterizing the intrinsic frequency dispersive nature of normal metals at room temperature. This engineering approach dramatically simplifies the otherwise complex analysis and allows for a much deeper insight to be gained into the classical relaxation-effect model. Three example applications are given for the calculation of important parameters and associated errors with hollow metal-pipe rectangular waveguides (MPRWGs), hollow MPRWG cavity resonators and single metal planar shield.
Keywords: Engineering approach, Terahertz dispersion, Metals.
