An approach is proposed to reduce mutual coupling between two closely spaced radiating
elements. This is achieved by inserting a fractal isolator between the radiating elements. The …

This letter presents a new metamaterial-based waveguide technology referred to as ridge
gap waveguides. The main advantages of the ridge gap waveguides compared to hollow …

Metasurfaces are thin two-dimensional metamaterial layers that allow or inhibit the
propagation of electromagnetic waves in desired directions. For example, metasurfaces …

This study describes the design and experimental verification of the ridge gap waveguide,
appearing in the gap between parallel metal plates. One of the plates has a texture in the …

Metamaterials are understood to be artificially engineered materials that exhibit unusual or
difficult to obtain electromagnetic (EM) properties. Such properties would include negative or …

We study the wave propagation between two glide-symmetric metallic plates drilled with
periodic rectangular holes. A mode-matching method is proposed in order to derive …

Thin artificial surfaces that act as high frequency bandgap structures have been recently
studied for the design of gap waveguides, hard surfaces, and planar lenses. Here, we …

A method is presented, for the efficient derivation of the dispersion equation associated with
electromagnetic bandgap (EBG) structures composed by lossless frequency selective …

This communication demonstrates for the first time the capability to independently control the
real and imaginary parts of the complex propagation constant in planar, printed circuit board …
