Abstract
A microstrip structure comprising a conductive layer whose width varies in such a way as to obtain an effective dielectric constant, which presents a sinusoidal shape modulation. The propagation of electromagnetic waves in materials with electromagnetic properties, which varies along their propagation direction having desirable characteristics, such as the presence of frequency bands in which the propagation is allowed and of bands in which the electromagnetic waves are stopped.
