Abstract

In this paper, a research on conditions for resonance excitation in a homogeneous dielectric cylinder with square crosssection is conducted using a FDTD-method. It is shown that in a cylinder with square cross-section resonant modes similar to whispering gallery modes can be excited, which helps in reducing the transverse dimensions of the focal spot. FDTD-method demonstrates an acceptable accuracy of the resonant mode detection.
