Advanced Study on Very High Q-factor Based on G-shaped Resonator Type Metamaterial Absorber

Abstract

High Q-factor based on absorption can be achieved by tuning (the reflection and the transition percentage). In this work, the simple design and simulated in S-band have been investigated. The simulation results of G-shape resonator are shown triple band of absorption peaks (60%, 91.5% and 70.3%) at resonance frequency 2.7 GHz, 3.26 GHz, and 4.05 GHz respectively. The results exhibited very high of the Q-factor (271) at resonance frequency (3.26 GHz). The high Q-factor can be used to enhance the sensor sensing, narrowband band filter and image sensing. The proposed G-shaped resonator has significant potential in practical applications, especially when it scaling to THz such as detection, imaging and sensing.
