Field consideration of focusing waveguide applicator for deep microwave hyperthermia / Harun Mohamed

Microwave hypothermia using waveguide appplicators has gained popularity because of the desirable heating characteristic of this type of heating modality. This project investigates the feasibility of using Dielectric Open-ended Rectangular Waveguide Direct-contact Antenna (DORWDA) array for depositi...
