Title: The Innovative Contributions of Roger Duquenoy in Gyromagnetic Devices
Introduction: Roger Duquenoy, based in Livry Gargan, France, has made significant strides in the field of gyromagnetic devices, holding two distinct patents. His research and innovations primarily focus on miniaturized devices operating at ultra-high frequencies. Duquenoy's contributions not only demonstrate his expertise but also reflect a commitment to advancing technology in this specialized sector.
Latest Patents: The latest patents by Roger Duquenoy include a **Method for Assembling a Miniaturized Gyromagnetic Device** and a **Miniaturized Gyromagnetic Device**. The former pertains to a gyromagnetic device, such as an insulator, that operates at ultra-high frequencies ranging from 1-40 GHz. The assembly process requires precise positioning, which is achieved through bonding. In his invention, the conducting core and two ferrite wafers are held by dual internal ground plates that form a positioned assembly. One of these plates features tongues that fit into slits of the other, ensuring accurate part positioning. The assembly process involves stacking a pressure washer, magnet, pre-positioned assembly, and base plate within a casing, followed by a single electric weld to close the device.
The latter invention, the **Miniaturized Gyromagnetic Device**, features an integrated design where a center conductor is placed between dielectric wafers and ferrite conductors, resulting in a circular inner configuration. This innovation also involves a pressure washer welded to a square casing, accommodating a magnet, wafers, and ferrite conductors alongside a pair of ground plates, which help absorb thermal expansion during operation.
