Abstract: In this paper, a novel solution based on Associated
Hermite polynomials finite-difference time-domain (AH-FDTD) method is
proposed to analyze the field-to-transmission line coupling problems.
Incorporated with the AH transformation, the method is suitable for dealing
with the frequency-domain parameters in transmission line (TL) equations, no
convolution integral is involved with. And it is an unconditionally stable
scheme, not limited by the Courant condition. Numerical results show that
the proposed method is agreeable with the frequency-domain solutions.
Keywords: Associated Hermite polynomials, coupling, FDTD, field-to-transmission line
