Abstract
The far-field patterns of microdisk resonators are analyzed by using t he finite-difference time-domain (FDTD) method and the near-to-far fie ld transformation, A brief summary of FDTD and details of the transfor mation in the cylindrical coordinate system are presented, Using FDTD, the wavelengths and Q values of the resonant modes are calculated fro m an impulse excitation, The steady-state field solutions are calculat ed from sinusoidal sources. The far-field patterns of an ideal microdi sk are presented.
