When a particular class of partially coherent light is incident upon a circular aperture, the on-axis spectrum of the light in the far zone is different from the spectrum of the light at the aperture.

Radio frequency interference (RFI) remains a critical challenge in synthetic aperture radiometry, where precise reconstruction of brightness temperature maps is essential for environmental ...

In today’s hyper-connected world, GNSS signals face unprecedented threats from jamming and spoofing attacks. As these signals traverse 20,000 km from satellites to Earth, they become vulnerable to ...

This May, the 4th Circular and Self-Amplifying RNA Therapeutics Summit (previously known as 'Next Generation RNA Therapeutics Summit) is landing back in Boston, as the unique opportunity to unite with ...

In a dramatic Women’s College World Series elimination game on Sunday, June 1, UCLA and Tennessee battled in a high-stakes softball showdown that nearly ended in controversy.

Abstract: Analytical expressions for the electromagnetic scattering in the far-field zone of an electrically small circular aperture in an infinite conducting screen with zero thickness were derived ...

The Sony 600mm is ideal for bird photography. The lens features 11 aperture blades, a 0.14x maximum magnification, and a close focusing distance of 4.5m. The 600mm has a filter diameter of 40.5mm ...

If you’re sure you need a wider, constant aperture or weather sealing, Canon does make several good L-series wide-angle zooms, including the 10–20mm f/4 L IS STM, 14–35mm f/4 L IS USM, and ...

This book deals with the fundamentals of wave optics, polarization, interference, diffraction, imaging, and the origin, properties, and optical effects of turbulence in the Earth's atmosphere.

We demonstrate both theor. and numerically that the proposed CPL can convert an incident circular polarization beam with prescribed chirality into a long centrosym. focus with a size beyond the ...

A localized diffraction-limited spot when the focal plane coincides with the particle plane and characteristic interference features between the incoming and scattered waves are observed. In the ...
