Title: Innovations of Thomas D Mantei

Introduction

Thomas D Mantei is a notable inventor based in Cincinnati, OH, who has made significant contributions to the field of plasma technology. With a total of three patents to his name, Mantei's work focuses on enhancing plasma production methods, which have applications in various industries.

Latest Patents

Mantei's latest patents include a plasma producing structure and a magnetic plasma producing device with an adjustable resonance plane. The plasma producing structure features a half-height waveguide that transmits microwave energy into an evacuated chamber. This design includes adjustable spacers that control the distance between the waveguide opening and the window, as well as a return piece adjacent to a permanent magnet. These improvements promote plasma uniformity at the workpiece, allowing for the use of smaller magnets and reducing stray magnetic fields outside the resonance zone. The transition of microwaves from a rectangular to a circular transmission mode outside the chamber enhances tuning and impedance matching.

The magnetic plasma producing device operates by transporting microwave energy at approximately 2.45 GHz into an evacuable chamber. A permanent magnet is centrally located above the chamber's opening, creating a strong downward magnetic field that aligns with the microwave propagation path. This configuration allows electrons to gain sufficient energy to dissociate molecules of the working gas into atoms, forming plasma that can perform work on a workpiece.
