Latest Patents

One of his latest patents is a "Microwave resonator for operation in the whispering-gallery mode." This invention features a resonant element included in a flat disk, which has a diameter considerably larger than its thickness. The electromagnetic wave propagates within the disk, confined between its periphery and a caustic surface, preventing radiation to the exterior. This resonator can be placed on a dielectric or metallic substrate, and it can be hollowed out within the caustic surface. Additionally, a resonator can be simulated within the thickness of a dielectric substrate using at least one metallic ring that forms a magnetic short-circuit with the ground plane. Excitation is achieved through microstrips or dielectric image waveguides.

Another notable patent is the "Frequency-doubling voltage-controlled oscillator." This VCO operates in the microwave frequency range and features two channels that work in parallel. Each channel contains a transistor mounted as an oscillating system, with energy collected on the drain electrode. The output currents of the two transistors are in opposite phase, which helps reduce FM noise near the carrier. Phase opposition is achieved through a varactor connected between the gates of the transistors, decoupled in direct current by two capacitors. To enhance the frequency range, two additional varactors can be mounted on the source circuits of the transistors.
