Metamaterials are commonly known to make things invisible. As artificially structured metal-
dielectric composites mimicking natural materials they exhibit properties that are not …

The electromagnetic characterization of materials is a fundamental problem in many
research areas of Electromagnetism. The goal is to determine the electrical permittivity and …

The growing development in the new communication technologies requests devices to
perform new features or to improve the old ones. The trend is to develop new artificial …

A chiral medium constituted by a two-dimensional lattice of eight cranks of the same
handedness is studied and found that it exhibits a huge electromagnetic activity, circular …

Here we present the experimental characterization of a new material constituted by an array
of four same handedness three-dimensional cranks impressed on a dielectric substrate …

The paper deals with the study of flux density through a newly proposed twisted clad guide
containing DB medium. The inner core and the outer clad sections are usual dielectrics, and …

A new EBG (Electromagnetic Band Gap) structure with chiral crank elements is presented
and its effects on the electric field propagation along a microstrip line are analysed and …

The periodical distribution of elements forming a bi-or three-dimensional periodical lattice
has provided a fundamental tool to develop new materials with exotic and, sometimes …

A review of the manufacturing techniques for developing chiral media based on the
inclusion of cranks is presented. Chirality is usually obtained by a randomdistribution of …

A new structure consisting of four cranks, as the unit cell, to produce electromagnetic activity
at microwave frequencies is proposed. A chiral medium is build by means of a 2D periodical …
