Methods and apparatus for microwave thermotherapy based on slow-wave systems

One of the perspective directions of slow wave systems usage is possibility of their implementation in biology and medicine as antennas and radiators for radio-frequency and microwave physical therapy, a radiothermy and a tomography, sensitive elements for medical diagnostics, devices for sterilization and heat treatment. Advantages of slow wave systems usage in biology and medicine are based on electrodynamic and design features of structures which follow from distribution of an electromagnetic field near their surfaces. Here we are looking for features for usage of slow wave systems on area with high value of dielectric permeability, in particular to biofabrics, and also the problems related to creation of electrodes for intracavitary microwave physical therapy on slow wave systems with primary concentration of electric field in biofabrics, adjacent to electrode surface. In this article the results of modeling microwave radiator on the basis of a ribbed coaxial line were received using Ansoft HFSS v.12 and CST Microwave Studio 2011 software.
