Universal metamaterial absorber
2017 11th International Congress on Engineered Materials Platforms for Novel Wave Phenomena (Metamaterials), 2017 We propose a design for an universal absorber, characterized by a resonance frequency that can be tuned from visible to microwave frequencies independently of the choice of the metal and the dielectrics involved. An almost resonant perfect absorption up to 99.8 % is demonstrated at resonance for all polarization states of light and for a very wide ...

Dual broadband metamaterial absorber
Optics Express, 2015 We propose polarization-independent and dual-broadband metamaterial absorbers at microwave frequencies. This is a periodic meta-atom array consisting of metal-dielectric-multilayer truncated cones. We demonstrate not only one broadband absorption from the fundamental magnetic resonances but additional broadband absorption in high-frequency range using ...

Manually tunable ventilated metamaterial absorbers [PDF]
Applied Physics Letters, 2021 For most acoustic metamaterials, once they have been fabricated, their operating frequencies and functions cannot be adjusted, which is an intrinsic barrier for the development of realistic applications. The study to overcome this limit has become a significant issue in acoustic metamaterial engineering.
