Abstract :
The author applies the Neumann series method to the combined integral equation. An important goal of this work is to find an iterative method which is useful for wavelengths much smaller than the scatterer. One application of the result is to determine corrections to physical optics. Particularly interesting examples are those to which physical optics is a poor approximation, even in the high-frequency limit. An example of such a problem is shown.<>
