Title: The Innovations of Jean-Denis Schubert
Introduction
Jean-Denis Schubert is a notable inventor based in Verneuil sur Seine, France. He has made significant contributions to the field of electromagnetic wave technology, holding a total of 5 patents. His work has been influential in advancing the understanding and application of waveguide systems.
Latest Patents
Among his latest patents is a device designed for rotating the polarization of an electromagnetic wave at the exit from a waveguide. This invention focuses on a device that rotates the polarization of a polarized electromagnetic wave propagating in a first waveguide through a predefined angle. The device includes a second waveguide with a lateral port, allowing the polarized electromagnetic wave to propagate between the first waveguide and the second via a coupling orifice. This orifice is smaller than the cross-section of the first waveguide and is geometrically adapted to facilitate electromagnetic coupling. Another significant patent is a pseudo-elliptical filter for the millimeter band using waveguide technology. This filter consists of positively coupled resonant cavities, with the signal input and output of each cavity positioned at 90 degrees to each other. The design includes retro-coupling of signals between cavities via a waveguide, making it applicable for pseudo-elliptical filters operating in the millimeter band.
