Metamaterial-based High-Performance Radar Absorbing Structure,e theory of absorption (based on electric and magnetic resonances) has been well explained through multiple interference theory. The last section of the chapter presents the mathematical modelling of the metamaterial absorbers. All the characteristics such as absorption, polarization insensitivity,

Active Metamaterial Frequency Selective Surface (FSS) Based Tunable Radar Absorbing Structure (RAS)to their high switching speed, wideband tuning, low cost, and compact size. Electronically regulated active components, viz. varactors, p-i-n diodes are mounted across the gaps etched in the FSS designs and their variable characteristics are precisely regulated by applying required biasing voltages.

Compact and Broadband Printed Antennas,rtains to the millimeter wave antennas where metamaterial inspired configurations are used. Here, the term broadband antenna is associated with those antennas which provides consistent impedance bandwidth i.e., the return loss <10 dB (Voltage standing wave ratio-VSWR <2) and consistent radiation ban
