Chapter 6 Metamaterial absorbers: from theory to practical implementation
-
Mohammad Rashed Iqbal Faruque
Abstract
This chapter explores the comprehensive study of metamaterial absorbers, providing a detailed understanding from historical evolution to practical applications. Fundamental aspects of metamaterial absorbers are carefully explored, elucidating the fundamental principles underlying their performance. Defining and isolating are key principles driving metamaterial absorbers, providing a solid foundation for understanding their operational mechanisms. Motivated by the imperative need for radar cross-section (RCS) reduction and electromagnetic interference (EMI) shielding, this chapter describes compelling reasons for the adoption of metamaterial absorbers in this important domain. Central to the practical implementation of metamaterial absorbers is their optimization in design. This section analyzes methods to optimize the design parameters ensuring the performance and effectiveness of these absorbers under various electromagnetic conditions. Theoretical exploration is seamlessly transformed into empirical validation through extensive simulation results. Using simulations, the chapter presents compelling evidence demonstrating the effectiveness of metamaterial absorbers in RCS reduction and EMI shielding across a spectrum of frequencies. Through meticulous experiments, the chapter proves the claims of RCS reduction and EMI shielding, lending to the practicality and effectiveness of these absorbers.
