Temporal equivalent of the Sommerfeld half-plane problem
Asma Fallah, Shixiong Yin, Andrea Alù +1
Sommerfeld's half-plane problem, describing diffraction of a monochromatic wave by a semi-infinite perfectly electric conducting (PEC) infinitesimally thin plate, is one of the cor…

Nonreciprocal Response of Electrically Biased Graphene-Coated Fiber
Asma Fallah, Nader Engheta
Here, we theoretically investigate the nonreciprocal response of an electrically biased graphene-coated dielectric fiber. By electrically biasing the graphene coating along the fib…

Nonreciprocal guided waves in presence of swift electron beams
Asma Fallah, Yasaman Kiasat, Mário G. Silveirinha +1
Breaking the reciprocity of electromagnetic interactions is of paramount importance in photonic and microwave technologies, as it enables unidirectional power flows and other uniqu…
