Abstract :
An original approach is proposed to predict and to take into account the frequency variation of the P-matrix parameters in the simulations. The proposed method is applied to well known Rayleigh and dispersive leaky waves for validation. The computed dispersion laws are compared to experimental results for different kinds of substrates and waves.
