The COM-based API and the integrated VBA like macro language allows a seamless merging of external synthesis tools and µWave Wizard™. Also the µWave Wizard™ can be controlled by any software and compiled language which include COM capabilities. Users can write their own macros to steer µWave Wizard™ as a background engine. For example, the user can setup his own routines to generate individual horn antenna profiles, tapers, convergence tests, or couplers with multiple apertures. Templates in source code are available and can be modified for certain applications.
