Abstract :
In this letter, an unconditionally stable finite-difference time-domain(FDTD) scheme based on weighted Laguerre polynomials(WLP) for solving cylindrical structures is proposed. The validity of the proposed formulations is shown through a numerical example of radiating in cylindrical coordinates.
