Design for simplified materials in transformation electromagnetics

In this chapter we review some of the common methods used to simplify the design of transformation electromagnetics devices. One of the major challenges is the complexity of the needed material parameters, and a variety of analytical, numerical, and approximation techniques can be used to create devices that still perform well, although not ideally, but are much easier to fabricate. All of these techniques are a manifestation of the general concept that transformation electromagnetics designs are relatively robust to material perturbations.
