z] = [beta] + /a is the complex propagation constant
, and c is the frequency.

According to lossless transmission line theory, the propagation constant
of a CRLH TL is given by [gamma] = j[beta] = [square root of Z'Y'], where Z' and Y' are the per-unit-length impedance and per-unit-length admittance, respectively.
The propagation constant
[beta] in the normalized form formula of the [TE.
To confirm the weak dispersion of this transmission line, we have reported the evolution of the imaginary propagation constant
versus the frequency in the 10-100 GHz (Figure 6) and seen the linearity of this parameter as a function of the frequency.
The complex wave mode implies that the phase constant and the attenuation constant of the propagation constant
are both nonzero.
If the propagation constant
of the incident light in dielectric medium is matched with that of the SP at metal-dielectric interface the surface plasmon polariton (SPP) mode is generated.
This equation relates the propagation constant
of SW [k.
The complex propagation constant
is determined and so the complex value of relative permittivity.
The design of LWA with variable serial capacitance obtained with RF-MEMS technology creates a variation of the propagation constant
(S) permitting the scanning-beam of the antenna from the broadside to close endfire direction.
Cables can be regarded as weakly lossy with real valued characteristic impedances and simplified expression for the complex propagation constant
Transmission lines, their general circuit model, impedance, propagation constant
and attenuation are the subject of Chapter 5.
