RCS reduction technique for reflectarray antennas
Electronics Letters, 2003 The performance of a concentric ring reflectarray element backed either by a solid metal ground plane or a frequency-selective surface is compared. Simulated and measured results show that the ‘in-band’ reflection phase response of the two structures is similar; however, the periodic surface reduces the ‘out-of-band’ reflectivity of the antenna by more

AIChE Journal, EarlyView.Abstract Electrification of distillation offers a promising route to reducing scope‐1 emissions from one of the chemical industry's most energy‐intensive unit operations. However, conventional adiabatic columns are dynamically inflexible: Long, energy‐intensive start‐ups make shutdown and restart impractical under variable electricity prices and ...

Stable Neural Signal Recording Processed by Memristor‐Based Reservoir Computing System
Advanced Intelligent Systems, EarlyView.This work introduces a memristor‐based reservoir computing (RC) system for real‐time, energy‐efficient processing of neural signals in brain‐machine interface (BMI). Combined with flexible mesh neural probes with tissue‐like flexibility and subcellular‐scale features that enable consistent, long‐term tracking of single‐cell neural activities, the ...

1-Bit Reconfigurable Transmitarray Antenna with Out-of-Band RCS Reduction
Applied SciencesStealth reconfigurable transmitarray antennas (RTAs) are essential components in wireless communication and radar detection systems. Therefore, in this study, we propose a 1-bit RTA with out-of-band radar cross-section (RCS) reduction.
