Una aproximación numérica en el dominio del tiempo al comportamiento de medios quirales realizados en circuito impreso

Abstract

The growing development of the new communications technologies requests devices to perform new features or to improve the old ones. The trend is to develop new artificial materials reproducing well-known properties already present in other frequency ranges (such as optics) or materials with properties inexistent in the nature. Among the first kind, artificial chiral media, based on the inclusion of particles with chiral symmetry into a host medium are worth to mention. Recently, we have considered new fabrication techniques based on the Printed Circuit Board (PCB) technology, because the use of via holes gives a great additional flexibility to select the type of chiral inclusions from helix to cranks. In this work, a numerical study in the time domain of the EM wave propagation through such a structure is achieved using the commercial software MEFiSToTM.
