Abstract
A new technique to estimate the scattering loss due to sidewall surface roughness amplitude and sidewall angle for
trapezoidal cross section waveguide has been demonstrated. The proposed technique has been based on the modified
Tien’s formulation for scattering loss mechanism as a mathematical model and combination of effective index method and
beam propagation method for problem solving tools. The simulated results have been compared with previous researchers
and mutual agreement has been observed.
