How Emmy Noether's theorem uses the Lagrangian to provide a formula for calculating the quantity of symmetries in a ...
The dorsal S-duct inlet of a HALE blended wing body UAV faces complex unsteady disturbances during operation. This study numerically investigates its aerodynamic response to gust excitations. Using ...
Frequency Diverse RIS (FD-RIS) Enhanced Wireless Communications via Joint Distance-Angle Beamforming
Abstract: The conventional reconfigurable intelligent surface (RIS) assisted far-field communication systems can only implement angle beamforming, which actually limits the capability for ...

Abstract: In this paper, we propose a novel integrated sensing and communication (ISAC) transmission framework based on the spatially spread orthogonal time frequency space (SS-OTFS) modulation by ...
Conventional spectroscopic ellipsometry is a powerful tool in optical metrology. However, when it comes to the characterization of non-periodic nanostructures or structured fields that are much ...
