Tunable High‐Performance Metamaterial Filters Based on Novel SRR Architectures

. Furthermore, by adjusting the unit cell geometry, SM-1 demonstrates a passband coverage of nearly 70%. Simulations identify two distinct filtering mechanisms: one driven by capacitive gain from local field superposition and the other by capacitive-inductive impedance matching, both of which enable efficient, low-loss transmission of electromagnetic energy. These metamaterials hold great potential for precise signal transmission and enhanced mobility in lightweight systems, making them promising candidates for advanced electromagnetic filtering systems.
