WebJul 9, 2024 · where k o is free space wave number. The wave impedance of a chiral background is taken to be η = η o (μ r /ε r) 1/2 where η o is intrinsic impedance of the free space. It is clear fromequations ()–() that both wave numbers are positive provided that $\kappa ^{2}_{r} \lt $ 1 [Reference Lindell, Sihvola, Tretyakov and Viitanen 22].In this … WebDec 3, 2024 · Those are intrinsic properties of space. Capacitance and inductance when excited by time varying source (like EM wave) they behave as if they were resistors (impedance). The only difference is that those resistors do not dissipate power as a real resistor does. That is why a plane wave is not attenuated while it is traveling in free space.
