Transformation optics has inspired numerous conceptual devices since the first theoretical model of invisibility cloaks. However, the transition of these concepts into industrial applications is now widely acknowledged as a challenging bottleneck. A practical design strategy that can be adopted by industrial engineers is thus desirable at this stage. Here we propose an integrated design strategy imposing practical constraints on the area-preserving affine coordinate transformation as a general practical method to solve the problem of nonmagnetism. Practical concerns related to fabrication, such as anisotropy degree and bending angles, serve as additional constraints to the transformation. As a specific example, we illustrate how to apply this practical strategy to the design of a two-dimensional electromagnetic waveguide bending adapter. Our study is a significant step toward practical use of ideal transformation optics devices that can be implemented with natural dielectric materials.
