Multiobjective Optimization Techniques

Designing an electronic system is an engineering task that requires the satisfaction of a given set of specifications, or constraints, over the system behavior. For example, in a waveguide bandpass filter, in-band ripple and out-band rejection are typical requirements, whereas the overall length of the device might be constrained to be smaller than a given length. In an amplifier, amplification and efficiency are the requirements; in an antenna design, the radiation pattern is often required to comply to a mask or to several masks in multiple-beam array design, while keeping the antenna geometry simple and economic is of course highly desirable.
