Patent number: 11522285Abstract: A method for beam steering and beam forming an antenna is disclosed herein that includes illuminating an optical fiber with a light source, thereby transmitting a signal through the optical fiber to an electro-optical switch. The electro-optical switch is actuated with the signal from the light source, thereby switching an electrical load in the electro-optical switch. At least one antenna element in an array of antenna elements is excited with RF radiation radiated by a driven element via an RF transmission line and reradiated from parasitic elements, thereby beam steering and beam forming the antenna.Type: GrantFiled: August 26, 2021Date of Patent: December 6, 2022Assignee: United States of America as represented by the Secretary of the NavyInventors: Marcos Ontiveros, Ayax D Ramirez, Stephen D Russell, Michael P Daly

Patent number: 10512425Abstract: An apparatus, method and system for dermatologically noninvasive testing for blood sugar concentration using an interferometry optical design. The present apparatus, method and system are used to measure the optical properties of blood, without puncturing the skin or drawing blood samples. They incorporate the use of an electromagnetic light source and two optical polarizers. A dermatological sample, e.g., the earlobe, webbing between fingers, is illuminated with polarized electromagnetic light. When the linearly polarized light passes through this dermatological sample, the blood in the dermatological sample acts as an optical rotator due to the optical interaction with the blood sample. The presence of molecular chirality in the blood sample induces optical activity. After the skin is illuminated, a second polarizer finds the orientation of the polarization by maximizing the intensity on the photo detector. As a result, the blood sugar concentration may be determined.Type: GrantFiled: August 4, 2016Date of Patent: December 24, 2019Assignee: United States of America as represented by the Secretary of the NavyInventors: Bienvenido Melvin L.

Patent number: 10381506Abstract: An optoelectronic device is provided that includes a doped substrate, a tunneling barrier, a direct bandgap two dimensional semiconductor material, a hot electron emitter, a gate electrode, and a voltage bias. The hot electron emitter injects hot electrons from the underlying substrate into the conduction band of the direct bandgap two dimensional semiconductor material via quantum tunneling. The gate electrode is operable to provide the voltage bias in a direction normal to the X-Y plane of the direct bandgap two dimensional semiconductor material so as to generate an electric field perpendicular to the direct bandgap two dimensional semiconductor material. The voltage bias provided by the gate is operable to change an optical bandgap of the direct bandgap two dimensional semiconductor material continuously from the visible to the mid-infrared spectral regime via an electric dipole layer enhanced Giant Stark Effect for electrically-tunable hot electron luminescence applications.Type: GrantFiled: May 23, 2018Date of Patent: August 13, 2019Assignee: United States of America as represented by the Secretary of the NavyInventors: Carlos M.
