Analysis of Snow and Water Effect on EBG Waveguides for Microwave Snow Melting to Prevent Electromagnetic Wave Leakage

To prevent microwave leakage during snow melting, introducing an electromagnetic bandgap (EBG) structure into a waveguide has been proposed. Since the bandgap frequency shifted with the surrounding medium, EBGs optimized for snow and water were designed and evaluated using FDTD simulations. The results confirmed the effectiveness of the EBG-embedded waveguide in managing electromagnetic field distributions for both snow and water.
