Our study will allow any orientation between the wave and boundary, and will also include the important cases of multiple boundaries. We will also study the practical case of waves that carry power over a finite band of fre ...

However, since the calculation of lens surfaces is based on specific input and output beam shapes, the whole system can only work well for the single input–output combination. In addition, the technique can do nothing to reduce the effect of spatial noise and imperfections ...
