Calculations of dispersion for Rectangular-core dielectric waveguides and of coupling length for directional couplers by weighted Residual method
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.
