Abstract
In this paper, we present numerical analysis of terahertz (THz) surface plasmon polaritons propagating in a parallel plate configuration. A planar metal surface has the ability to support loosely bound surface waves, called Zenneck waves at terahertz frequencies. Two parallel metal plates separated by a narrow vacuum region can lead to the highly confined terahertz surface plasmon modes at specific frequencies. The frequency of the terahertz mode can be changed with a change in the gap between the plates. Further, we observed that the carrier concentration of plates strongly effect the frequency of the terahertz mode as well as its properties. We have examined in detail the dispersion properties of the terahertz surface plasmons supported by the parallel plate configuration with a varying gap width as well as carrier density of the plates.
Highlights
Terahertz radiations cover a narrow range of frequencies between optics and microwave region in the electromagnetic spectrum
Several waveguide geometries have been examined both experimentally and numerically in last more than a decade, parallel metal configuration has been one of the most promising and widely explored techniques as it has proven its potential in applications such as imaging, sensors and strong field confinement
Mueckstein and Mitrofanov [11] have studied THz surface plasmon waves excited on a gold surface by a focused beam
