In reality, most design optimization problems involve computationally expensive analysis. The aim of this work is to develop methods that can simultaneously deal with estimates arising from multifidelity analysis codes.
Optimization problems involve maximization/minimization of certain performance objectives such as maximization of strength, maximization of fuel efficiency, minimization of weight, etc.
The non-conventional propagation characteristics of left hand transmission lines (LH TL) offer a new degree of freedom for the design of high frequency wave-guiding and wave-radiating components.
