| Abstract: | We studied the modified pure imaginary wave number of Helmholtz equation in impedence boundary condition,which contains a single corner to solve the closed regional problems.Single layer and double layer potentials were used to represent its solution and solve its domains.Finally,the numerical example illustrated the feasibility and reliability of this method. |
