Abstract
The spectral index method (SIM) for analysis of the rib waveguide in a ir is improved by including the singular behaviour of the principal fi eld component in the vicinity of the reentrant corners, thereby giving the singular SIM (SSIM). This generally improves the value of the mod al propagation constant as compared with more exact solutions. The new approach is successfully extended further to the rib waveguide couple r.
