Calculated dispersion of a heterostructure with a zigzag interface constructed by a lattice with Ca = 200 nF and Cb = 100 nF at the upper domain and a lattice with Ca = 100 nF and Cb = 200 nF at the lower domain. Other parameters are C = 100 nF, C1 = C2 = 10 nF, L = 1.043 micro H and Rs = 30 Omega. The colors denote the imaginary part of eigenfrequencies.
