Solar Terminator Waves Revealed as Dominant Features of Upper Thermospheric Density

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Observations of solar terminator waves (STWs) in thermospheric mass density (TMD) measurements above 500 km reveal STWs as dominant features of the upper thermosphere. While previous investigations have shown that STWs in the middle‐lower thermosphere have amplitudes on the order of 6%–8% of the background TMD in that region, this study shows ...

Film‐Based Multi‐Photon Lithography for Efficient Printing of Electromagnetic Surface Structures

Advanced Materials Technologies, Volume 10, Issue 11, June 5, 2025.
This work introduces film‐based multi‐photon lithography as an efficient method for fabricating electromagnetic surface structures with 2D and 2.5D geometries, particularly THz and mid‐IR metasurfaces. These structures can be fabricated on various substrates, such as glass or silicon‐on‐insulator, over areas ranging from mm2 to cm2, achieving feature ...

Femtosecond Pulse Shaping with Semiconductor Huygens' Metasurfaces

Advanced Optical Materials, Volume 13, Issue 16, June 6, 2025.
Spatially variant silicon Huygens' metasurfaces enable femtosecond pulse shaping by tailoring the spectral phase and amplitude of incident pulses. Two key functionalities are demonstrated: temporal stretching and pulse splitting of an input Gaussian pulse.
