Abstract
This paper presents a step-by-step procedure to extract the effective permittivity of dry and wet snow in an electromagnetic simulator. The S-parameters are extracted using HFSS (High Frequency Structure Simulator), which is a Finite Element Method (FEM) full wave simulator. The permittivity curve is calculated using the S21 retrieval method. The calculated permittivity is compared with theoretical mixture models (Maxwell Garnett and Bruggeman Symmetric) with a verification that it lies between the effective permittivity theoretical bounds.
