Abstract

We study the wave functions and transmission properties of an open microwave cavity in the frequency range of 1–17 GHz. The transmission of microwaves between the input and output antennas of the cavity is found to exhibit large fluctuations as a function of frequency, while the cavity wave functions are found to reveal the presence of periodically recurring scars, in close correspondence with specific peaks in the Fourier transform of the transmission fluctuations. This work, therefore, provides strong support for the results of recent studies of open quantum dots, which have revealed the presence of measurable transport results associated with specific wave function scars.
