Applicator for Superficial Microwave Hyperthermia Filled with Anisotropic Dielectric Media: Numerical Investigation of Design Degrees of Freedom

摘要

In this paper properties of an rectangular-waveguide applicator (test applicator) for superficial microwave hyperthermia filled with stratified isotropic and/or anisotropic dielectric media are discussed. Man-made biaxial anisotropic material is considered here. Electric field distributions in a cross-section of the test applicator filled with anisotropic material are compared with the test applicator filled completely with water and with the one partially filled with water and partially with high permittivity materials. Furthermore, for some applicators power loss densities in the virtual phantom of muscle tissue are numerically estimated.
