The characteristic impedance
of a transmission line at high frequencies--[Z.
In the literature, the characteristic impedances
of unshielded S&IM lines are calculated by using a formula depending on the effective permittivities of unshielded S&IM lines and characteristic impedance
of a conventional microstrip line.
where [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] is the phase delay of line of characteristic impedance
The attenuation could also be reduced by a thicker line metallization or by increasing the line width and so decreasing the characteristic impedance
The presence of one or other characteristic impedance
depends on the type of simplification used in the deduction of each different model.
Using the classical definition of the characteristic impedance
as the square root of the ratio between the impedance and the admittance:

A transfer-matrix approach for estimating the characteristic impedance
and wave numbers of limp and rigid porous materials.
When the characteristic impedances
of the coupled line are 50 [ohm], the normalized even-mode characteristic impedance
is the inverse of that of the odd-mode--[z.
The amount of reflection is a function of load impedance, RL, and the characteristic impedance
, Zo, of the line.
