The full-vectorial finite-element-based imaginary-distance beam-propagation method (IDVFEBPM) is applied to perform modal analysis of lossless and lossy microwave dielectric waveguides. The excellent agreement between the results obtained using the IDVFEBPM and those in the literature reveal its hig

## Abstract A threeβdimensional finiteβelement time domain scheme based on the envelope approach is presented for the first time. In this approach the fast wave component or carrier is removed from the field and the envelope is solved instead. This strategy permits longer time steps than when the c
Using a full vectorial finite element based beam propagation method combined with the imaginary axis propagation technique, the accurate calculation of the full vectorial leaky modes of a curved optical waveguide is addressed. The numerical precision of the proposed modal solution approach is suppor
