Abstract
This investigation describes the design and performance of two, water-immersed, microwave applicators (433 MHz) for use with photoacoustic ultrasonography (PAUS). A cylindrical, open-aperture waveguide was chosen because it could be integrated easily into our PAUS instrumentation. The microwave flux distributions for two microwave applicators were measured using a specially-constructed temperature probe, consisting of an optical fiber with a temperature-sensitive phosphor that was placed inside a thin, polyethylene tube filled with 0.5 M saline. Using this instrumentation, we mapped the microwave flux distribution for each applicator. The physical characteristics of these applicators are discussed.
