Simulation of near-field generated by s-band rectangular horn antenna array for hyperthermia therapy applications using 4nec2 software

Project (M.S., Electrical and Electronic Engineering) -- California State University, Sacramento, 2010.

Project (M.S., Computer Engineering) -- California State University, Sacramento, 2010.

This project will focus on the application of advanced electromagnetic simulation software 4nec2, for the near-field characterization of a 3-element S-band array of horn antennas, operating at the ISM frequency of 2.4 GHz. Previous modeling efforts have shown a significant difference between simulated and measured data. The key effort in this project will be to minimize the difference between simulated and measured data using 4nec2 software. This study has useful application in the area of clinical hyperthermia, which is defined as the therapeutic treatment of tumors in the body by heating caused by focused RF or microwave radiation. The 3-element array consists of a central focusing element and two surrounding directing elements. The focusing element can be axially adjusted and surrounding elements are fixed to focus the beam of a required point, which is necessary in hyperthermia treatment.
