During this talk, I will discuss the highly unusual and intriguing optical properties of Epsilon-near-zero (ENZ) materials. It has been shown that perfect coupling can be achieved between two waveguides through a very narrow ENZ channel of arbitrary shape and length. The associated large field enhancement of highly squeezed fields in the thin ENZ channel was also considered for enhanced nonlinear optical interactions, such as optical switching and bistability. ENZ materials were also employed for antenna directivity and radiation pattern control, thermal emission control, and coherent perfect absorption …
