A broadband and polarization-insensitive high-impedance surface (HIS) metamaterial
absorber (MA) based on octagonal ring-shaped resistive patches is presented. The …

In this article, a comprehensive review of published techniques for reducing radar cross‐
section (RCS) of a target in various military and industrial applications is presented. This …

A 1-D phased array based on a dual-artificial magnetic conductor (AMC) ground is proposed
in this letter. Initially, the relationship between the reflection, radiation, and scattering …

High-impedance surfaces are artificial surfaces synthesized from periodic structures. The
high impedance is useful as it does not short circuit electric currents and reflects electric …

This letter defines a physical-bound-based array figure of merit for both single and multiband
array antennas. It provides a measure to compare their performance with respect to return …

Because of the design limitations of conventional high-impedance surfaces (HIS), it is not
possible to miniaturize the HIS and increase the bandwidth, simultaneously. To overcome …

The electromagnetic performance of flight vehicles has been attracting considerable interest
in recent years. As one of the important indicators of this performance, radar cross section …

Artificial magnetic conductor (AMC) in the form of a partially corrugated internal wall of a
metal enclosure is applied to optimise our pioneered liquid crystals filled partially shielded …

In this letter, the equivalent circuit method is employed to derive an upper bound for the
bandwidth of ultrathin absorbers comprising high impedance surfaces. It is found that the …

The general properties of a frequency selective surface loaded with negative impedance
converter (NIC)‐based active loads are discussed from a theoretical perspective. The …
