Abstract
A microwave cavity experiment to measure the phase difference θ0 between two points of a filed distribution inside the resonator was performed. As such, the technique was applied to the superposition of two eigenmodes on a path to an EP. According to this, it represents the first experimental observation of a mode in a microwave resonator, where the electric field oscillates with a phase difference of 90° at two different points.
