Detailed Description
The invention at hand is an RF-optical all-dielectric metamaterial based upon dielectromagnetic spheres. It provides higher efficiency with no metallic loss, at any desired frequency. It is thus applicable for many RF-optical applications. The proposed metamaterial has great significance for the RF and optics field, improving upon the performance of many electronic and optical devices. Current technology is based on metallic inclusions, and is not suitable for RF and optical devices. Loss is a major issue for optical metamaterials. Low-loss metals and high refractive index dielectrics will greatly boost this field, but are extremely hard to find. Current technology is also difficult to fabricate, due to periodicity that determines performance. This is a young and growing field, and this invention offers a potential improvement on what is currently available.
