| Abstract: | In this paper, using the weighted residual method (WRM), we derive mathematical formulas for calculation of dispersion characteristics and field distributions of guided modes of the strip dielectric waveguides and strip-loaded dielectric waveguides, and formulas for calculation of coupling length of rectangular-core dual channel directional couplers. The derived formulas are simple and easy to use, and the results are more accurate than those of other approximate analysis. |
