Patent number: 11791566Abstract: A multiferroic antenna apparatus and method are described which provides increased energy efficiencies and ease of implementation. Magnetoelastic and/or magnetostrictive resonator are coupled to a piezoelectric substrate, along with electrodes coupled to its opposing surfaces. In receive mode the resonators create mechanical waves in response to being excited into magnetic oscillation by receiving electromagnetic radiation, and these mechanical waves coupled to the piezoelectric substrate causing it to generate an electrical output signal at said electrodes. In transmit mode an electrical signal coupled through the electrodes induces mechanical waves in the piezoelectric substrate directed to the resonators which are excited into magnetic oscillation to output electromagnetic waves.Type: GrantFiled: February 4, 2021Date of Patent: October 17, 2023Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Abdon E. Sepulveda, Gregory P. Carman, Jinzhao Hu, Joseph Devin Schneider, Elmer Wu, Zhi Yao, Sidhant Tiwari, Wenzhong Yan

GYROMAGNETIC NONLINEAR TRANSMISSION LINE FOR RADIO FREQUENCY SIGNAL GENERATION AND PULSE COMPRESSION
Publication number: 20230198116Abstract: Disclosed are non-linear transmission lines using ferromagnetic materials to generate ferromagnetic resonance oscillations. In one aspect, a non-linear transmission line apparatus is disclosed. The apparatus includes an outer conductor having a first side and a second internally facing side, and an inner conductor positioned internal to the non-linear transmission line apparatus. The apparatus further includes a ferromagnetic material surrounding the inner conductor, wherein the ferromagnetic material comprises nanoparticles of an ?-polymorph of iron oxide expressed as ?—Fe2O3. The apparatus also includes a first dielectric material positioned between the outer conductor and the inner conductor, the dielectric material in contact with both the ferromagnetic material and with the second internally facing side of the outer conductor, wherein the outer conductor, the inner conductor, the dielectric material and the ferromagnetic material form the nonlinear transmission line.Type: ApplicationFiled: December 20, 2021Publication date: June 22, 2023Inventors: Joseph Devin Schneider, Alexander Adrian Baker, Jinkyu Han, Lars F.

Patent number: 10851914Abstract: A strained bilayer film with reinforcing members is used to open and close gas flow outlets in a microvalve array. The bottom layer of the bilayer film is compressive and the top layer is tensile. Reinforcing members are made from compressive material that accomplishes the dual objectives of reducing potential defects at the interface between the anchor region and the free region of the actuator, and controlling the stresses along the edges of the strained bilayer to avoid curling as the actuator unrolls from its normal coiled configuration in response to an applied voltage. Because of the configuration, the strained bilayer film occupies a minimal amount of space compared to other systems when the valve is opened, and it permits a higher density of microvalves to be utilized. Optional supports are provided over gas flow channel openings to increase the area over which the voltage is applied, increasing electrostatic stability of the actuators in maintaining their unrolled state for a variety of uses.Type: GrantFiled: May 3, 2019Date of Patent: December 1, 2020Assignee: UNIVERSITY OF LOUISVILLE RESEARCH FOUNDATION, INC.Inventors: Shamus McNamara, Joseph Devin Schneider
