Single and multiple layers of sub-wavelength periodic Babinet complementary patterns composed of rounded nano-object miniarrays were investigated. In case of illumination with linearly and circularly ...

Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics. These engineered materials offer precise control over lights behavior, but ...

Experiments at Lawrence Livermore National Laboratory's National Ignition Facility (NIF) require breathtaking precision. Each of the 192 lasers is focused to a width of a few millimeters to enter a ...

LAES measurement using circularly polarized light. A femtosecond laser pulse and an electron pulse were fired at an argon gas beam at the same time, giving a scattering signal whose energy and angular ...

Metal halide perovskites have emerged as leading candidates for next-generation optoelectronic materials owing to their remarkable optical tunability and processability. However, achieving ...

The challenges of fabricating micromotors and geartrains with comparable size to a human cell. The problems of powering such motors. How metasurfaces allow projected laser output to power these ...
