A new general method for treating wave propagation and scattering problems in partially limited domains with curved boundaries is established, based on an enhanced local-mode series, which includes an additional term accounting for the effects of the curved boundary. The additional mode provides an implicit summation of the slowly convergent part O (n−2) of the local-mode series, rendering the remaining part to converge much faster, like O (n−4), where n is the mode order.
