Modeling of electrodynamic parameters of microwave sterilizer

For the sterilization of medical instruments, a technology for their immersion heat treatment with intense microwave radiation at frequency 2,45 GHz is analyzed. The advantages this in comparison traditional methods are shown. An electromagnetic model sterilizer surgical tools was built, taking into account temperature dependence complex dielectric permittivity medium (water). A rectangular cavity waveguide excitation used as its basic unit. With help numerical on finite element method, values reflected and absorbed power, well heating rate water an operating power 600 W, were determined. analysis thermal processes, performed according to simplified showed rather high efficiency such device, which provides given frequency.
