Abstract
A wavefront transformer for reflecting and transforming an incident electromagnetic wavefront includes an electrically-conductive substrate with spaced perforations (cavities), which may have uniform spacing and varying depth. The perforations may have a radius that is close to and greater than a cutoff radius for one or more intended incident frequencies of the incident wavefront. The spaced perforations may be filled with air or may be filled with a dielectric solid material. The substrate may be covered with a cover made of a dielectric solid material. The transformer may be made by drilling holes in the substrate. Alternatively a plate having protrusions on it corresponding to the desired perforations may be used to form the perforations on the substrate. The plate may be removed or left in place after the formation of the perforations.
