Abstract: A solution of the impedance wedge diffraction problem has been given by Malyuzhinets in reference. The key to the problem is the solution of Malyuzhinets functional equations. However, how to get the solution of the functional equations is not given in reference. A detailed process to get the solution of the functional equations is provided by using the infinite product thory in reference, but in which there are some errors and indistinct places.
In this paper these errors in reference are corrected and another simpler method to get the solution of the functional equations is also provided for the purpose of comparison.
