JFET_V7_N3_RP2 Analytical Expression for Dispersion Properties of Circular Core Dielectric Waveguide without computing (d^2 ß)/(dk^2 ) Numerically S.K. Raghuwanshi Santosh Kumar Journal on Future Engineering and Technology 2230 – 7184 7 3 26 34 Waveguide Dispersion, Index of Refraction, Velocity, Eigen Value 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. February - April 2012 Copyright © 2012 i-manager publications.
