Terahertz emission from the intrinsic Josephson junctions of high-symmetry thermally-managed Bi<sub>2</sub>Sr<sub>2</sub>CaCu<sub>2</sub>O<sub>8+δ</sub> microstrip antennas

ORAL

Abstract

We show for high-symmetry disk, square, or equilateral triangular thin microstrip antennas respectively obeying C∞v, C4v, and C3v point group symmetries, that the transverse magneti electromagnetic cavity mode wave funcitons are restricted in form to those that are one-dimensional representations of those respective point groups. Plot of the common nodalpoints of the ten lowest-energy non-radiating two-dimensional rrepresentations of each of these three symmetries are presented. For comparison with symmetry-broken disk intrinsice Josephson junciton microstrip antennas constructed from the highly anisotropic layered superconductor Bi2Sr2CaCu2O8+δ (BSCCO), we present plots of the ten lowest frequency orthonormal wave funcitons and of the angular distributions of the emission power. These results are compared with previous results for square and equilateral triangular thin microstrip antennas.
