“…In combination with deal.II the finite element library [20,21,22] MiTMoJCo becomes a powerful tool for modeling of realistic 2D Josephson junctions. The need to go beyond the 1D model arises in studies of transmission line intersections and networks [23,24,25,26,27,28,29,30], curved waveguides [31,32], radial soliton-like excitations [33,34,35,36,37,38], superconducting chaotic oscillators [18], beam splitters [39], 2D fluxon oscillations modes [40,41,42,43], fluxon qubits [44,45,46,47] and other systems.…”
