The effective anisotropic conductivity of the CFRP laminate was obtained from experimental waveguide attenuation measurements over the entire X-band [16].
Here for the first time is presented dependencies of the complex longitudinal propagation constant [h.bar] = h'- ih", where h' is the phase constant and h" is the waveguide attenuation constant (losses) on the percentage of light hole [N.sub.l] and heavy hole [N.sub.h] concentrations and the operating frequency f.
