چکیده
This paper presents a multi-bit reconfigurable intelligent surface (RIS) with high phase resolution, capable of beam-steering in the azimuthal plane at sub-6 Gigahertz (GHz). Field trials realistic indoor deployments have been carried out, coverage enhancement performance ascertained for three common wireless communication scenarios. Namely, serving users an open lobby mixed line sight and non-line conditions, via junction between long corridors, multi-floor scenario propagation windows. work explores potential deployment to mitigate effects communications. In single transmitter, receiver link, received power improvement as much 40 dB is shown be achievable by suitable placement RIS, instantaneous bandwidth least 100 MHz possible over 3 4.5 GHz range. addition, resolution on optimal reception RIS experimentally verified, 2.65 compared 1-bit case.

متن کاملAn Experimental Study of the Effect of High Electric Field on Mass Transfer Enhancement
Applying corona wind as a novel technique can lead to a great level of heat and mass transfer augmentation by using a very small amount of energy. The enhancement of forced flow evaporation rate by applying electric field (corona wind) has been experimentally evaluated in this study. Corona wind produced by a fine wire electrode charged with positive high DC voltage impinges on water surface an...
متن کاملInverse scattering for high-resolution interferometric microscopy.
We extend the applicability of inverse scattering for optical coherence tomography (OCT) to the case of high numerical aperture focusing optics. We include the effects of tight focusing so that the approach is applicable to any interferometric microscopy method. The applicability to modalities, such as OCT and optical coherence microscopy, enables computed reconstruction of three-dimensional vo...
