Corrected impulse invariance method in Z-transform theory for frequency-dependent FDTD methods
The classical impulse invariance method in Z-transform theory is found to be incorrect and inaccurate when the impulse response is discontinuous at intial time t = 0. Such inaccuracy results in higher numerical errors if it is used to develop the update equations for frequency-dependent finite-diffe...
