Frequency-selective analysis of THz photonic elements by the ac Josephson effect

Here we report the results of terahertz photonic elements frequency analysis by the ac Josephson effect. We considered planar resonators. There were observed excitation of fundamental and dipole resonance modes in photonic elements by Josephson oscillations of YBa
