Wireless link has need of an omnidirectional antenna like dipole, but with higher gains. Of
course, there is no way of achieving both of them simultaneously. To solve this contradiction …

An ultrawideband metamaterial slab (meta-slab) covered antipodal Vivaldi antenna (AVA)
with high-gain and stable radiation patterns is presented. The meta-slab exploiting the …

In this paper, we present a new horn antenna that can mechanically reconfigure the beam
direction and polarization by combining a traditional linearly polarized horn antenna with an …

In this paper, a high gain, aperture efficient, low profile compact, near zero index (NZI)
metasurface (MS) lens antenna with enhanced radiation characteristic is proposed. A high …

In this paper, we propose a strategy to achieve a single-feed multi-beam metasurface
antenna by combining phase gradient and coding sequence. Theoretically, the multi-beam …

Boosted by the progresses in nanooptics, highly sensitive and label-free optical transducers
for sensing applications have been proposed over the last years. Among them, plasmonic …

This paper presents a solution to overcome the inherently limited bandwidth of substrate-
integrated waveguide (SIW) slot antennas. It is analytically shown that by decreasing the …

A metamaterial slab covered antipodal Vivaldi antenna (MSAVA) is proposed to improve the
radiation properties of the antipodal Vivaldi antenna (AVA). The metamaterial covers (MCs) …

In this paper, a conical horn antenna in the presence of a metamaterial lens in the X‐band is
introduced and fabricated. The annular metamaterial lens is located at the aperture of a …

In this paper, a new high-gain antenna with beam control based on multilayer non-uniform
metasurfaces (MNMSs) is proposed. The MNMS consists of multilayer non-uniform square …
