We have developed a symbolic representation of an intrinsic Josephson junction stack to enhance the scalability of equivalent circuit simulations for Josephson Plasma Emitters (JPEs) of a superconducting terahertz source in LTspice. The symbol features four ports, enabling the integration of both the electrical and thermal parts of the equivalent circuit. Utilizing this symbolic representation, the stacking number of intrinsic Josephson junctions in the simulation can be easily adjusted, and the thermal part of the equivalent circuit can be independently modified, improving the scalability and flexibility of JPE simulations.
