Terahertz emission from pie-shaped wedge microstrip antennas of the high-$T_c$ superconductor Bi$_2$Sr$_2$CaCu$_2$O$_{8+\delta}$

ORAL

Abstract

We calculate the standing wave functions for pie-shaped wedge microstrip antennas of various wedge angles $\phi_0$. We then calculate the emission distributions from the uniform Josephson current and from the excitation of a cavity mode generated from the stand wave functions. For a narrow dieter's pie slice, quantitative fits to the experimental data on a Bi$_2$Sr$_2$CaCu$_2$O$_{8+\delta}$ narrow isosceles triangular mesa are shown.
