An overview about mutual coupling analysis in antenna arrays is given. The relationships
between array impedance matrix and embedded element patterns, including beam coupling …

We derive from first principles an accurate homogenized description of periodic
metamaterials made of magnetodielectric inclusions, highlighting and overcoming relevant …

Metamaterials (MTMs), which are formed by embedding inclusions and material
components in host media to achieve composite media that may be engineered to have …

In this paper, physical concept and performance analysis of all-dielectric metamaterials are
presented. Metamaterials with desired material parameters (±ε,±μ) are developed by …

We investigate dispersion properties of a hexagonal dielectric periodic structure that can be
used to engineer dielectric graded-index lenses. The connection between the geometry of …

Asup erstrate layer is used to enhance the directivity of the small radiation sources such as
Microstrip Patch Antennas. In this paper, we use square loop frequency selective surface …

In this work, results are given for controlling waves arbitrarily inside a new type of spatially
variant lattice. To demonstrate the concept, an unguided beam was made to flow around a …

This article investigates the dispersion properties of metasurfaces with hexagonal lattices,
including potential higher symmetric configurations. We explore the relationships between …

The notion of artificially engineered materials, which has a long history dating back to the
late part of the 19th century, gained considerable momentum two decades ago. The …

We demonstrate focusing of a plane microwave by a planoconcave lens fabricated from a
photonic crystal having a negative refractive index and left-handed electromagnetic …
