Optimal Condition for Strong Terahertz Radiation from Intrinsic Josephson Junctions

Feng Liu, Shi-Zeng Lin, Xiao Hu

In order to enhance the radiation power in terahertz band based on the intrinsic Josephson junctions of Bi${}_2$Sr${}_2$CaCu${}_2$O${}_{8+\delta }$ single crystal, we investigate a long cylindri…
