so that the CNN allows the quick near-field positioning (NFP), and there is no need for huge computing overhead. Therefore, the proposed AWPN is a multifunctional and highly integrated system that fully utilizes the advantages of the metasurface...
Simple nanostructures were evaluated and found to localize near-fields within a very small volume in the lateral surface8. On the other hand, gap-based structures such as bowties are known to decrease the localized volume even further5,9–11. The SP-based near-field localization has been ...
Watching the skiers come down to the base at Palisades Tahoe © Karen Rubin/goingplacesfarandnear.com From the Village base, you can’t appreciate just how vast Palisades Tahoe resort. Unlike most ski mountains (especially in the Northeast), where you can see the trails meander from the su...
The diameter of the field of view is 30 mm. The spectral range is 910–2200 nm with a spectral resolution of 8 nm. The wavelength accuracy is less than 0.5 nm, and the wavelength repeatability is less than 0.05 nm [30, 31]. 2.2. NIR Spectra Acquisition An intact ...

It is therefore crucial to understand the process of the image forma- tion for a variety of nanophotonic structures of different complexity and sizes. Plasmonic nanostructures, being deeply-subwavelength and lossy, are commonly investigated in the near-field regime11–13. So far several geometries, ...
3D acoustic wave field cloaking has been the subject of quite a few studies since the pioneering works of Refs15,16,17. Such systems are getting increasingly more refined as the detection methods become more sophisticated. Considerable attention has been recently paid to the cloaking systems that ...
Although the total SCSs for PEC cylinders, showing a general scattering performance in all directions, can drop to a low level, the calculation of bistatic scattering width is still necessary for us to understand exactly the far-field scattering distribution. In Fig. 2(a), the scattering perform...
