Characteristic Impedance

$Z\_0\; =\; \backslash sqrt\{\backslash mu\; \backslash over\; \backslash epsilon\}\; =\; \{1\; \backslash over\; \{c\; \backslash \; \backslash epsilon\}\}$

$Z\_0\; \backslash$is the characteristic impedance

$\backslash mu\; \backslash$is the magnetic permeability of the medium

$\backslash epsilon\; \backslash$is the electric permittivity of the medium

$c\; =\; \{1\; \backslash over\; \backslash sqrt\{\; \backslash mu\; \backslash epsilon\}\}\; \backslash$ is the speed of propagation in the medium

$Z\_0=\backslash sqrt\{\backslash mu\_0\; \backslash over\; \backslash epsilon\_0\}\; =\; \{1\; \backslash over\; \{c\; \backslash \; \backslash epsilon\_0\}\}\; =\; 376.730313461...\; \backslash \; \backslash Omega$

here $c\; =\; \{1\; \backslash over\; \backslash sqrt\{\; \backslash mu\_0\; \backslash epsilon\_0\}\}\; \backslash$ is the speed of propagation in vacuum.
