With its unique and exclusive linear and nonlinear optical characteristics, epsilon-near-zero
(ENZ) photonics has drawn a tremendous amount of attention in the recent decade in the …

In this article, a type of multiport power divider is proposed based on the concept of epsilon-
near-zero (ENZ) metamaterials. An arbitrarily shaped ENZ metamaterial comprising a …

Metamaterials can be defined as a joint of small artificial cells or elements which could be
small scatterers or apertures which are distributed in a regular array throughout a region of …

This article presents a novel substrate-integrated waveguide (SIW) antenna with a
designable broadside pattern at a length-irrelevant operating frequency, which is inspired …

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 …

This article presents two miniaturized multimode waveguide bandpass filters (BPFs) based
on epsilon-near-zero (ENZ) channel concept. By connecting parallel shorting stubs on the …

This paper presents a wideband leaky-wave substrate-integrated waveguide (SIW) slot
antenna. The proposed structure comprises slots loaded with a low-index metamaterial …

This chapter presents gain and bandwidth enhancement techniques for THz planar
microstrip antennas. Four models were designed, and the simulation results are presented …

This paper presents a broadband dual-polarized substrate integrated waveguide (SIW) slot
antenna. It is analytically shown that by decreasing the permittivity of a dielectric-loaded slot …

This paper proposes a novel and efficient design technique to achieve multi‐frequency
impedance matching. The matching network is mainly constructed based on fragment …
