Spinning Metasurfaces

Spectro-polarimetric imaging in the long-wave infrared (LWIR) region plays a crucial role in applications from night vision and machine perception to trace gas sensing and thermography. However, the current generation of spectro-polarimetric LWIR imagers suffers from limitations in size, spectral...

Andy Schramka and Peter Menart win the NDSEG fellowship

Our group members Andy Schramka and Peter Menart have recently been awarded the prestigious National Defense Science and Engineering Graduate fellowship by the Department of Defense. DoD plans to award new three-year graduate fellowships each fiscal year to individuals who have demonstrated ability...

New Antenna Tech to Equip Ceramic Coatings with Heat Radiation Control

The gas turbines powering aircraft engines rely on ceramic coatings that ensure structural stability at high temperatures. But these coatings don’t control heat radiation, limiting the performance of the engine. Researchers at Purdue University have engineered ceramic “nanotubes” that behave as thermal antennas, offering control over the spectrum and direction of high-temperature heat radiation.

Non-classical photonic spin texture of quantum structured light

Classical structured light with controlled polarization and orbital angular momentum (OAM) of electromagnetic waves has varied applications in optical trapping, bio-sensing, optical communications, and quantum simulations. However, quantum noise and photon statistics of three-dimensional photonic...
