Title: Avner Cahana and Radiofrequency Diamond Grading

Introduction

Avner Cahana is an inventor associated with Kfar Truman, Israel, and Ariel Scientific Innovations Ltd. His work includes a patented approach to assessing diamonds with radiofrequency and terahertz electromagnetic fields. The supplied information lists 1 patent for Cahana.

Latest Patents

Cahana’s listed patent is titled “Method and Device for Grading Diamonds Using Radiofrequency (RF) Spectroscopy.” It describes a method that places a diamond in a grading device and applies an electromagnetic field at frequencies up to 30 THz. The device records the resulting modulated signal as S-parameters, processes its amplitude or phase information, and uses calculations and a computer algorithm to relate the measurements to nitrogen concentration, boron concentration, or plastic deformation. These results can then be used to grade the diamond.

The described device includes an RF generator, transmitting and receiving antennas, a waveguide, an amplitude and frequency detector, and a computing unit. The invention’s stated purpose is to provide a way to evaluate diamond characteristics through electromagnetic measurements.
