Abstract
A miniaturized microwave probe has been developed using the microwave-caused heating of a thin coating of a resistive material and the resulting change in the color of a miniscule amount of liquid crystal in intimate contact. The probe can be inserted in animals for microwave biological effects research and is isotropic in its sensitivity to different polarizations of the fields.
