Abstract :
A mechanical finite element code is incorporated into a diffraction synthesis code to enable direct synthesis of a reconfigurable dual offset reflector antenna. Contour beam in terms of the actuator amplitudes and positions. The code allows realistic modeling of real reflector surfaces using the mechanical properties of the surface material. A description of the code is given and an example of a dual offset reflector antenna with a fixed shaped main reflector and an adjustable subreflector is shown.
