Emulating one-dimensional resonantQ-matching behavior in a two-dimensional system via Fano resonances

Abstract

Through detailed numerical and analytical studies, we establish that the significant enhancement of thermal emission via $Q$ matching, which has been possible in one-dimensional (1D) systems only, can be extended to two-dimensional (2D) systems by means of Fano resonances in the 2D system. In particular, we show the existence of essentially 1D behavior in a 2D system---a case of reduced dimensionality. Moreover, we show how properties of these spectra can be controlled by changing the geometrical parameters of the 2D system.
