Coherent superposition of light from subwavelength sources is an attractive prospect for the
manipulation of the direction, shape and polarization of optical beams. This phenomenon …

This article demonstrates a new design concept of 3-D printed multilayer vertically integrated
composite right/left-handed (VI-CRLH) transmission lines (TLs) with compact size …

A general design for a non-radiating dual-band N-way series power divider (SPD) is
presented in this paper. The non-linear phase responses of composite right and left handed …

A dual-band phased array antenna prototype for the Federal Communication Commission
automotive short-range radar and long-range radar operating at 25.5 and 76.5 GHz with a …

This article presents a novel approach to shrink the size of the conventional phased array
antenna fed by Butler matrix. The proposed size reduction of the phased array antenna is …

This paper presents an all-passive phased-array feed network based on composite right/left
handed (CRLH) transmission lines (TLs). A CRLH TL enables systematic engineering of the …

Supporting wide-band circular polarization (CP) over broad bandwidths poses a significant
challenge for patch antennas and arrays. In any CP antenna, not only must the antenna's …

A novel frequency-scanning antenna array using dual-band bandpass filters (BPFs) as
phase-modulation components is proposed. First, the phase performances of BPFs with …

In this paper, a wide-angle frequency-scanning array antenna is presented for three-
dimensional (3D) radar. Initially, a modified composite right/left-handed (CRLH) unit cell …

A Ku-band, electronically-steerable, artificial-impedance-surface antenna (AISA) was
designed, fabricated and measured. It is capable of scanning in elevation from-70° to 80° …
