Abstract :
Dielectric mirrors have recently been proposed to be a key component for future wireless terahertz communication systems. Here, we examine the dispersion properties of a reflector that consists of nine layers with two different materials. The refractive index of the layers differs considerably. The mirror is highly reflecting and omnidirectional in a very extensive frequency band. We find that the group delay is in the order of picoseconds inside the frequency band of interest (330- 370 GHz), which is a reasonable value for such a component.
