An electromagnetic model for multilayer planar structure with single slot was built in spectral domain. Numerical techniques were discussed for its numerical solution, to deal with the problems of singularity and oscillation in the numerical integration in spectral doman, etc. The calculation time is greatly reduced by a series of numerical techniques such as dividing integrand into two different parts,simplifying the function for large arguments, dividing integration regions appropriately, etc. The solution is convergent and reasonable.
