Index modulation (IM) in orthogonal frequency division multiplexing (OFDM) systems represents a transformative approach in modern communications. This technique utilises the indices of active ...

We all know that it’s sometimes better to beg forgiveness than ask permission to do something, and we’ll venture a guess that more than a few of us have taken that advice to heart on occasion. But ...

A talk, The Unreasonable Effectiveness of the Fourier Transform, was presented by [Joshua Wise] at Teardown 2025 in June last ...

A new type of vortex beams with OAM-independent propagation overcomes historical limitations related to beam divergence, a breakthrough for optical communication The future of optical communications ...

Meta-holograms, the computer-generated holograms assisted with nano-structured metasurfaces, promise efficient recording of light at the nanoscale. Adopting the multiplexing principle further bestows ...
