Absorptive and Frequency-Selective Plasma Limiters

In the field of electronic circuits, ensuring signal integrity while protecting sensitive components from damage due to excessive signal levels is important. Limiter circuits may b-e used to handle issues by managing and controlling signal amplitude. Conventional limiter circuits often face challenges in accurately maintaining signal quality, especially...

Super-Directive Huygens Antennas based on Crossed Electric and Magnetic Dipoles

The antenna industry has experienced substantial growth in recent years due to escalating demands for high-speed connectivity and the proliferation of smart devices. Traditional patch antennas, which are widely used because of their low profile and ease of fabrication, typically achieve a gain of only about 2–3 dBi. A new super-directive patch...

Dielectric Anapole Microwave Plasma Jet

Project ID:TECH-2024-12 Cold plasma is a critical technology in many application fields, including microelectronic fabrication, plasma medicine, flow control, lighting, propulsion, and sterilization. However, generating stable plasma is not a trivial task as energy-hungry machines are often required. Currently, igniting and sustaining plasma is...

Super Resolution Imaging with Modulation of Point Spread Function

Project ID: TECH2024-09 High image resolution is a desired outcome in wave-related disciplines such as ultrasound, acoustics, optics, and electromagnetics. However, the spatial resolution of an imaging system is fundamentally limited by the spatial frequency of the point spread function (PSF) of the system due to diffraction. There have been numerous...

High-Efficiency Microwave Plasma Jet

Project ID: D2021-25 Background Plasma jets are currently made with bulky and expensive equipment that consumes a lot of energy. Most commercially available plasma jets utilize high-voltage pulses (e.g., 100s of V to kV) or high-power radio frequency (RF) sources (e.g., 10s of W), even though low-power plasma with effective surface power density...

Hybrid Electric Vehicle Energy Storage System

Project ID: ENG00204 Novelty: This invention provides both a combined battery/ultracapacitor energy storage system and battery chargers associated with these systems. First, it combines an ultracapacitor with a battery to optimally power both high current surges and more constant demands. The ultracapacitor provides the high current power, thereby...

Functionally graded graphene transient electronics

Project ID: D2018-22 Functionally Graded Graphene Transient Electronics Every year, 42 million tons of electronic waste pollute our planet. The industry is urgently seeking eco-friendly solutions that minimize environmental impact without sacrificing performance. Enter transient electronics, devices designed to disappear safely after use. Current...

Sensor for detection of ice accumulation and liquid water content in wet snow

Project ID# D2019-13BackgroundLiquid water content (LWC) of snow is the ratio of the weight of water contained to the total weight of the wet snow. LWC of snow influences its density, adhesion to surfaces, and snow cohesiveness which determines its stability, shedding, and melting runoff. Ice build-up can fall from structures, such as bridges, causing...

Tin whisker growth mitigation by using nickel oxide sublayers

Project ID: D2018-36 Metal whiskering is a problem with electrical devices in which the metal, such as tin, suffer from compressive stress or high work functions and grow hair-like structure that extend from the metal. This causes circuit shorts and electrical failures. Current solutions require the use of lead or conformal coatings to mitigate...

Inexpensive, Earth-Abundant, and Tunable Hole Transport Material for CdTe Solar Cells

Project ID: D2017-08Background Photovoltaic (PV) cells have been produced with a wide variety of materials for each functional layer. The typical PV is a substrate layer coated with a semiconductor layer and two ohmic contacts. Thin film solar cells use a thin absorbing layer, such as Cadmium telluride (CdTe). CdTe is the most eco-friendly, high efficiency,...
