Abstract

Waveguide dispersion can be tailored but not the material dispersion. Hence the total dispersion can be shifted at any desired band by adjusting the waveguide dispersion. Waveguide dispersion is proportional to and need to be found numerically. In this paper we have tried to compute analytical expression for in terms of. To compute accurately, should be accurate enough up to decimal point. This constraint sometimes generates the error in calculation of waveguide dispersion. In this paper we have tried to compute analytical expression for in terms of. It reveals that we can compute waveguide dispersion enough accurately for various modes having known only -

Keywords
