US Patent No: 5784682

System for separating constituents from a base material

---

Abstract

---

A system for separating constituents from a base material using RF energy which is coupled to a reaction chamber by way of a windowless transmission line. By eliminating the need for a window, traditional limitations placed on the maximum power delivered to the resonating cavity are eliminated. Thus, the only practical limitation on the RF energy which can be delivered to a resonating cavity are the ability of RF energy source to produce that energy and the ability of the resonating cavity to manage that energy.
