Among the different ways to solve Maxwell?s equations, integral-equation approaches are probably offering the most physical insight. They allow the prediction of surface waves and their transformation into leaky waves. We will explain how integral equations can be turned into a direct design tool, beyond traditional field analysis. This allows the design of metasurfaces with prescribed radiation patterns, as well as the creation of multi-beam metasurfaces. Such a perspective on numerical methods may also serve other fields of engineering.

Highly doped semiconductors are ideal materials to realize plasmonic and metamaterial based systems operating from the infrared to the THz frequencies. In this work, we show that nano-antennas, hyperbolic metamaterials and epsilon-near-zero metasurfaces can be designed which such materials. These systems are demonstrated to enhance light matter interactions and can be applied for infrared spectroscopy.
