Estimation of permittivity and conductivity in dispersive and attenuating media using multifrequency technique

This article proposes a technique based on multifrequency pulses, which are used to determine values for the physical medium interacting with the transmission of the electromagnetic waves. Parameters such as relative permittivity measurements of pulses at different frequencies. The proposed method has been simulated in a Debye medium where the relation between lineal dispersion and conductivity is known. The FDTD numerical method is used to calculate time lags and amplitudes in the electric field, providing data about propagating different signals in the medium given. Described here is a new technique for the study and treatment of electromagnetic wave interaction with the medium.
