Better than a lens -- Increasing the signal-to-noise ratio through pupil splitting
, 2022 Lenses are designed to fulfill Fermats principle such that all light interferes constructively in its focus, guaranteeing its maximum concentration. It can be shown that imaging via an unmodified full pupil yields the maximum transfer strength for all ...

Unified Framework and Comparative Analysis of Delay-Doppler Communication Systems
IEEE Open Journal of the Communications SocietyDelay-Doppler (DD) system translates a time-varying channel into quasi-static time invariant channel by modulating the information in DD domain. This serves as a core principle behind orthogonal time frequency space (OTFS) and orthogonal delay Doppler ...

Angewandte Chemie, EarlyView.We report on a suitable approach to predict the chirality “strength” and efficacy of chirality transfer from chiral nanoshape solutes to an achiral discotic nematic (ND) liquid crystal solvent. Highly efficacious chirality transfer based on shape commensurability between nanoshape solute (in the form of gold nanodiscs, GNDs) and a ND solvent was ...

The MIMO-OTFS Technique in the Next 6G Communications
Engineering AccessThe orthogonal time-frequency space (OTFS) technique is a promising method of waveform modulation that encodes data in the delay-doppler (DD) domain. OTFS distinguishes itself from conventional multiplexing methods by employing two-dimensional modulation
