Abstract: This paper presents a frequency-tunable multi-ring microstrip antenna (MR-MSA) fed by an L-probe with varactor diodes. In order to realize a frequency-tunable multiband microstrip antenna, ...
Abstract: Intelligent Reflecting Surfaces (IRSs), renowned for their ability to reconfigure wireless signals, operate on the principle of dynamic phase tuning. The reflected signals are configured by ...
Directional transport of liquids is of great importance in microfluidics, biomedical engineering, and energy saving. Despite considerable progress in engineering various open surfaces to achieve ...
