Genetic Algorithms in Electromagnetics
Chapter One
Introduction to
Optimization in
Electromagnetics
As in other areas of engineering and science, research efforts in electromagnetics
have concentrated on finding a solution to an integral or differential
equation with boundary conditions. An example is calculating the radar cross
section (RCS) of an airplane. First, the problem is formulated for the size,
shape, and material properties associated with the airplane. Next, an appropriate
mathematical description that exactly or approximately models the airplane
and electromagnetic waves is applied. Finally, numerical methods are
used for the solution. One problem has one solution. Finding such a solution
has proved quite difficult, even with powerful computers.
Designing the aircraft with the lowest RCS over a given frequency range is
an example of an optimization problem. Rather than finding ... read full excerpt from Genetic Algorithms in Electromagnetics ebook
