On the microwave detection of dielectric bodies in a lossy medium with parallel-plate dielectric waveguide probe

This paper presents an experimental study on the microwave detection of spherical dielectric bodies exhibiting varying complex permittivity from the embedding lossy dielectric medium, simulating malignant tumors of different dielectric contrast from normal biological tissue. Measurements are performed using a flanged parallel-plate dielectric waveguide probe (PPDW) on phantom materials. Preliminary results demonstrate the potential of the PPDW to identify a malignant tumor embedded in normal tissue.
