Physical Optics and the Impedance Boundary Condition
Journal Title: American journal of Engineering Research - Year 2017, Vol 6, Issue 7
Abstract
Wave propagation is an important phenomenon in the context of mobile systems. From basic diffraction one can develop methods for objects that are used as models for obstacles in the path of propagation. In order to combine a number of objects, the method known as Physical Optics can be used. This method is mostly used for perfectly conducting surfaces but can be extended to surfaces described by means of an impedance boundary condition. It will be shown that targets that have impedance surfaces yield RCS results that are lower than the results of perfectly conducting surfaces. The results obtained are compared with exact methods and other approximation methods and they are in good agreement. Application of these results to stealth technology and wave propagation is discussed.
