This study deals with numerical and experimental investigations of a microwave thawing process.

The microwave power generation is calculated from Maxwell’s equations and then from Lambert’s law, using COMSOL Multiphysics. For those two different approaches, the heat source term depends on the dielectric properties of the material.

Numerical simulations are compared with experimental results carried out in a microwave waveguide.
