In this article, a number of guiding structures are proposed which take advantage of higher
symmetries to vastly reduce the dispersion. These higher symmetries are obtained by …

An efficient directive antenna is described that can be used to realize essentially non
dispersive links over extremely large bandwidths. The antenna is a significantly enhanced …

In this paper the ultrawide-band properties of a long slot array are described. The study
provides the rigorously derived Green's function (GF) for an infinite long slot array. From …

In this paper, the scanning performances of connected arrays that include backing reflectors
are investigated. The comparison between connected dipoles and slots is based on the …

This paper presents a simple and effective way to increase the scan range of phased array
antennas by using a metasurface (MTS) curved dome. The technique is based on a phase …

In this letter, we demonstrate that the dispersion properties associated with glide symmetry
can be achieved in systems that only possess reflection symmetry by balancing the …

A novel type of leaky-wave antenna is presented. Differently from previously reported leaky-
wave antennas, it is characterized by a constant beam direction over a very wide range of …

A superconducting microstrip half-wavelength resonator is proposed as a suitable band-
pass filter for broadband moderate spectral resolution spectroscopy for terahertz (THz) …

This work deals with the properties of a long slot array fed by an array of periodically located
feeds spaced at a Nyquist interval. The study begins with the rigorous Green's function (GF) …

This two-part sequence of papers deals with the analysis of artificial dielectric layers (ADLs).
ADLs consist of a cascade of planar periodic surfaces designed to realize dielectric slabs …
