Recently, artificially constructed metamaterials have become of considerable interest,
because these materials can exhibit electromagnetic characteristics unlike those of any …

Artificially engineered metamaterials are now demonstrating unprecedented
electromagnetic properties that cannot be obtained with naturally occurring materials. In …

Previous programmable metasurfaces integrated with diodes or varactors require external
instructions for field programmable gate arrays (FPGAs), which usually rely on computer …

A novel design of nearly perfect metamaterial absorber is proposed and analyzed for
terahertz sensing applications. The full vectorial finite element method is used to simulate …

In this paper, a new approach for the development of planar metamaterial structures is
developed. For this purpose, split-ring resonators (SRRs) and complementary split-ring …

&Quot; Analytical Modeling in Applied Electromagnetics provides a thorough introduction to
the use of analytical models in the design of antennas and microwave devices. By …

We study the behavior of wave propagation in materials for which not all of the principal
elements of the permeability and permittivity tensors have the same sign. We find that a wide …

In the past few years, new developments in structured electromagnetic materials have given
rise to negative refractive index materials which have both negative dielectric permittivity …

We report experimental results at 1.057 GHz that demonstrate the ability of a planar left-
handed lens, with a relative refractive index of-1, to form images that overcome the …

Decades ago, Veselago predicted that a material with simultaneously negative electric and
magnetic polarization responses would yield a 'left-handed'medium in which light …
