ZEPHIR

Physical optics code

Overview

ZEPHIR is a software based on the physical optics theory. It allows calculating the radar cross section of electrically large structures.

Methods

A triangle meshed structured is used to apply the PO technique completed with the PTD. The geometrical optic magnetic field is obtained with up to 5 reflections. The geometrical optics part is powered by RayBooster software developed by HPC-SA. This library provides a very fast ray/triangle intersection computation. ZEPHIR can be optionally hybridised with ICARE MoM software.

Interface

ZEPHIR is integrated onto the CAD software GID. The result is a user-friendly interface. The geometry can be directly designed with GID. GID's import features allow using most of the common CAD formats (IGES, DXF, VDA,…). A triangle mesh is generated by GID. It is directly used by ZEPHIR. The calculated RCS is available in a text file. To make its interpretation easier, it can also be directly visualized in the geometry.
