WitrynaWave impedance: It is defined as: η η μ η = η 0 ( μ r ϵ r) Where η 0 is the characteristic impedance. The value of μ r = 1 (if not given) η η η = η 0 ( 1 ϵ r) From, equation 3 we can write: η η = η 0 n. ∴ The wave impedance of a medium is equal to the wave impedance of free-space divided by the refractive index of the medium. WitrynaDespite the high refractive index provided by the hybrid labyrinthine meta- material, the relative acoustic impedance Z r always approaches unity with maximal value of 1.53 for different a.
