EM PLANE‐WAVE INDUCED THÉVENIN'S VOLTAGE ON TRANSMISSION LINES

This chapter provides illustrative applications of the electromagnetic (EM)‐reciprocity–based coupling models. For the sake of simplicity, it starts with the description of Thevenin's voltages induced by a uniform EM plane wave impinging on an idealized model of a transmission line above the perfect ground. Upon analyzing this specific example, it is shown that the coupling models are, indeed, fully equivalent. The chapter subsequently closely analyzes the EM plane‐wave induced Thevenin‐voltage response of a thin perfect electric conductor (PEC) trace on a grounded slab. It demonstrates that the reciprocity‐based coupling model is readily capable of providing the EM plane‐wave excited response of a narrow straight printed circuit board trace. The PEC trace under consideration is located just on the grounded slab. The slab shows a contrast in its EM properties with respect to the homogeneous, isotropic, and loss‐free embedding in its (real‐valued, and positive) electric permittivity only.
