Abstract
The present paper reports the analysis of the flow of power in a plana r dielectric guide with its surfaces having very small parabolic defor mation. Using the scalar wave approximation an eigenvalue equation for the flow of power in the core region has been derived which is then p lotted against the dimensionless core parameter showing the variation of power now in the main guiding region of the parabolic cylindrical w aveguide.
