Prof. Andrea Alu of CUNY Advanced Science Research Center

Metamaterials and metasurfaces are engineered structures with properties that go well beyond what offered by natural materials, providing unprecedented opportunities to tailor and enhance the interaction between waves and materials. In this talk, I discuss our recent research activity in this area of technology with special emphasis on the opportunities offered by metasurfaces for wireless applications. In particular, I will discuss how suitably tailored meta-atoms and arrangements of them open exciting venues to manipulate and control electromagnetic waves in unprecedented ways. I will discuss our recent work on metamaterials for scattering suppression applied to antenna technology, metasurfaces to control wave propagation and radiation, circulators and isolators that do not require a magnetic bias, and active metasurfaces for next-generation wireless systems. Physical insights into these exotic phenomena, new devices based on these concepts, and their impact on wireless technology will be discussed during the talk.
