Description 114-120
Evaluation of extinction cross-sections (ECS) of realistically distorted raindrop is carried out by using finite element method (FEM) on modified Pruppacher-and-Pitter (MPP) raindrop model for horizontal and vertical polarizations in centimeter and millimeter wave frequency range with mean raindrop radii from 0.025 to 0.35 cm. The results obtained from FEM are compared with existing models based on first order perturbation evaluation technique (FOPET) and volume integral equation formulation (VIEF) using MPP. The results obtained are in good agreement with the results of these models with 6% mean variation in horizontal polarization for both the models and 7% and 10% mean variations are observed in vertical polarization in these models respectively.
