Advance Metamaterials for Electromagnetic Wave Manipulation
The growing demands and advancements in wireless communication and radar systems need highly efficient signal manipulation, adaptive frequency control, and enhanced device performances. Metamaterials, composed of artificially engineered subwavelength unit cells, have emerged as a powerful platform by manipulating amplitude, phase, polarization, and energy dissipation beyond the limits of conventional materials. Absorption and polarization control represent two significant applications of electromagnetic metamaterials, where the co- and cross-polarized reflection coefficients play a critical role in determining overall device performance. This invited talk presents the design and development of multi-band, miniaturized, and wideband metamaterial absorbers, and then extended to multi-functional metamaterial structures that simultaneously realize high absorption and polarization manipulation within a single compact architecture. In addition, the talk also introduces the concept of absorptive filtering Reconfigurable Intelligent Surfaces (RIS), which integrate both tunable phase response and a bandpass like reflection response in the operating band with a sharp rejection in the out of band. Absorptive frequency-selective reflectors provide the multiple functionalities of absorption and reflection without the tunable phase response. However, absorptive filtering RIS requires a tunable phase response which can achieved by adding phase shifting layer.
