July 1, 2024 - University Park, PA - Prof. Douglas Werner, the John L. and Genevieve McCain Chair Professor of Electrical Engineering in the College of Engineering at Penn State, has been elected as Life Member of the Association of Old Crows (AOC). AOC states that 'The name "crow" emerged from the first large-scale use of Electronic Warfare during the WWII Battle of Britain and the US/Allied bombing raids over Europe. The Allied Radar Countermeasure operators used the code name “ravens” and employed receivers and transmitters to monitor and jam threat frequencies. Military jargon later changed “ravens” to "crows." Since that time, the defense of (and maneuver within) the Electromagnetic Spectrum (EMS) has been undertaken by "crows" across the military, government, industrial base, and academia. The Association of Old Crows provides a means of connecting members and organizations nationally and internationally across government, defense, industry, and academia to promote the exchange of ideas and information, and provides a platform to recognize advances and contributions in these fields.'

February 13, 2023 - University Park, PA - Reconfigurable antennas — those that can tune properties like frequency or radiation beams in real time, from afar — are integral to future communication network systems, like 6G. But many current reconfigurable antenna designs can fall short: they dysfunction in high or low temperatures, have power limitations or require regular servicing. To address these limitations, CEARL researchers combined electromagnets with a compliant mechanism, which is the same mechanical engineering concept behind binder clips or a bow and arrow. The proof-of-concept reconfigurable compliant mechanism-enabled patch antenna today can be found in our article in in Nature Communications.

August 2018 - Washington, DC - Tunable composite optical materials with tailored properties are highly sought after. The near-infrared and visible frequency ranges remain the most challenging for achieving strong and fast tunability. Authors of this work have demonstrated an optimized metamaterial made of a chalcogenide composite structure, which switches between high transmission and low transmission states without a substantial change in reflection. What is important is that in the amorphous phase the material has relatively low loss and the transmission is high. This gives the presented metamaterial an advantage over the metal-based structures, where losses are typically higher in the near-infrared range.
August 24 2018 - WASHINGTON, DC – Researchers at the Pennsylvania State University and Purdue University have implemented a generalized dispersion model (GDM) in a Discontinuous Galerkin Time Domain (DGTD) electromagnetic solver.

Their findings are published in Vol. 26, No. 22 of Optics Express (Optical Society of America). The paper is available online at doi:10.1364/OE.26.029005.

February 14, 2018 - Washington, DC – Researchers at the Pennsylvania State University have developed a theoretical framework for the design of single lenses capable of apochromatic performance (i.e., color correction for red, blue, and green light). This is done through the synergy of a gradient-index (GRIN) lens and a metasurface coating. It is shown that by exploiting the unique dispersion behaviors of lens surface, GRIN volume, and metasurface coating, one can achieve color-correcting performance that would typically require three lenses in conventional systems with only a single lens. Their findings are published in the February issue of Optica (Optical Society of America). The paper is available online at doi:10.1364/OPTICA.5.000099. The effort was supported by the DARPA/DSO Optics and Imaging (EXTREME) Program.

January 28, 2014 - University Park, PA – A specially formed material that can provide custom broadband absorption in the infrared can be identified and manufactured using "genetic algorithms," according to Penn State engineers, who say these metamaterials can shield objects from view by infrared sensors, protect instruments and be manufactured to cover a variety of wavelengths. "The metamaterial has a high absorption over broad bandwidth," said Jeremy A. Bossard, postdoctoral fellow in electrical engineering. "Other screens have been developed for a narrow bandwidth, but this is the first that can cover a super-octave bandwidth in the infrared spectrum." They reported their approach in the February issue of ACS Nano. Click here for the academic paper. For the full news story, see the links below.

March 28, 2013 - University Park, PA – CEARL researchers have published their findings on dispersion-engineered metamaterials using optimized nanofabricated deep-subwavelength structures. The design team looked at existing fishnet structured metamaterials and applied nature-inspired optimization techniques based on genetic algorithms. They optimized the dimensions of features such as the size of the fishnet and the thicknesses of the materials. One of the transformative innovations made by the researchers was the inclusion of nanonotches in the corners of the fishnet holes, creating a pattern that could be tuned to shape the dispersion over large bandwidths. They reported their approach in the March 28 online issue of Scientific Reports. Click here for the academic paper.

January 30, 2011- University Park, PA – Cheaper, lighter and more energy-efficient broadband devices on communications satellites may be possible using metamaterials to modify horn antennas, according to engineers from Penn State and Lockheed Martin Corp. "Existing horn antennas have adequate performance, but have undergone little change over several decades except for advances in more accurate modeling techniques," said Erik Lier, technical Fellow, Lockheed Martin Space Systems Co. "Modifications enabled by metamaterials can either enhance performance, or they can lower the mass and thus lower the cost of putting the antenna in space." Lighter antennas cost less to boost into space and more energy-efficient antennas can reduce the size of storage batteries and solar cells, which also reduces the mass.
