Mathematical analysis of some devices made using epsilon-near-zero materials

Speaker: Raghavendra Venkatraman, Mathematics, Courant Institute

Location: Warren Weaver Hall 1302

Synopsis:

"Epsilon-near-zero" devices are a class of photonic devices (novel waveguides, scatterers, resonators) that operate at a frequency at which one of their components has dielectric permittivity nearly zero. I'll discuss recent results, obtained in joint work with Bob Kohn, about their robustness, and their shape design.
