The analysis of unilateral finlines has been completed using a new method Regular Solution of Singular Integral Equation. Here

an integrating procedure is adopted and the uniqueness of the fields is determined by the regular conditions for the solutions of the singular integral equations at the edges of the metal strips. Numarioal results show that this method leads to more rapidly converging series solutions. Comparing with the best method spectral domain method

our method can obtain more accurate results with much less computer time. Comparing with the old singular integral equation technique

this method can get much more accurate results with less computer time

simpler formulae and clearer concepts.
