Millimeter-wave absorbers、Frequency-tunable structures

The use of wireless electronic devices, such as sensors, radar detectors and cell phones, has resulted in a complex electromagnetic (EM) environment that causes significant EM pollution. To avoid these, absorbers with effective EM attenuation are indispensable. Within the context, functional materials and structures having adjustable or adaptive absorption characteristics are of paramount importance to efficiently absorb EM radiation in challenging circumstances. Frequency-tunable absorbers are commonly employed in microwave frequency bands. Herein, we present a multiband millimeter-wave absorber comprising a multilayer hybrid structure of graphene-copper-FR4-copper to achieve multiband frequency-tunable millimeter-wave absorption. We emphasize on the theoretical framework, design methodology, and results based on simulations.
