Theory of impedance networks: the two-point impedance andLCresonances [PDF]
Journal of Physics A: Mathematical and General, 2006 We present a formulation of the determination of the impedance between any two nodes in an impedance network. An impedance network is described by its Laplacian matrix L which has generally complex matrix elements. We show that by solving the equation L u_a = lambda_a u_a^* with orthonormal vectors u_a, the effective impedance between nodes p and q of ...
