Title: The Innovations of Donald C. Schmadel
Introduction
Donald C. Schmadel is a notable inventor based in Kensington, MD, with a significant contribution to the field of optical technology. He holds five patents that showcase his expertise and innovative spirit. His work primarily focuses on measuring evanescent fields and developing advanced apparatuses for electromagnetic radiation.
Latest Patents
One of Schmadel's latest patents is titled "Process and apparatus for measuring an evanescent field in an optical." This invention describes a method to measure the strength of an evanescent field at the surface of an optical fiber. The process involves injecting light into one end of the optical fiber while contacting the tested portion with a material that has a higher index of refraction than the fiber itself. The amount of light lost, or coupled out of the fiber, is directly related to the strength of the evanescent field at the cladding surface. This loss can be correlated with optical fibers of varying cladding thicknesses to determine the cladding's thickness or the extent of its removal through etching. Another significant patent is the "Frequency shifted cavity for electromagnetic radiation," which presents a frequency-shifted cavity apparatus designed for electromagnetic radiation.
