The homogenization limit and waveguide gradient index devices demonstrated through direct visualization of THz fields
Electromagnetic homogenization approximation calculates an effective refractive index of a composite material as a weighted average of its components, and has found uses in gradient refractive index and transformation optics devices. However, the utility of the homogenization approximation is hinder...
