Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering
Advanced Photonics Research, Volume 6, Issue 5, May 2025.Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

Advanced Robotics Research, EarlyView.A novel carbon fiber reinforcement for dielectric elastomer actuators enhances actuation force while decoupling electromechanical performance from the actuator's aspect ratio. Unlike conventional fiber reinforcements, it enables a uniform planar stretch state along the entire actuator.

Eos, Transactions American Geophysical Union, 1984 The fiscal year 1985 budget for the solar system exploration program of the National Aeronautics and Space Administration (NASA) is very promising (m/5Eos, February 14, 1984, p. 49). As announced by the Office of Management and Budget, the document includes a new start‐up program lor the MGCO (Mars Geoscience Climatology Orbiter) mission. Mixed in with

Charged Clouds of Ionized Gas Emerge from Tribocharging Grains
The Planetary Science JournalIf two solid particles collide, charge is exchanged. However, this transfer is not restricted to the surface of the particle. Ions are also dispersed into the environment. They form a charge cloud around the particle.

Temperatures of Jupiter’s Upper Atmosphere: The Role of the Planetary Magnetic Field
The Astrophysical Journal LettersThe primary source of heating in the upper atmospheres (thermospheres) of giant planets has been the subject of long debate. The conundrum (or “energy crisis”) consists in observed thermosphere temperatures at low and midlatitudes exceeding values ...
