Design of a miniature microwave oven for biodetection applications.
The goal of this project is to design and build a small, portable, battery-operated microwave oven for application in the detection of biological warfare agents. Electromagnetic energy from a single mode will be used to heat a small sample in the microwave cavity. As part of this project we will investigate electromagnetic mode distribution as a function of sample volume and location, and we will study different methods to excite the modes in the cavity. Modeling work will be done using Ansoft's High Frequency Structure Simulator (HFSS). Experimental work includes the characterization of electromagnetic modes for different types of excitation, measurements of the temperature response inside the cavity and measurements of radiation (leakage fields) from the cavity.
