Abstract Metasurfaces with engineered phase discontinuity offer extra degrees of freedom to control the angular spectrum characteristics light and can be used construct planar metalenses a variety anomalous functionalities. Here, off‐resonance spin‐locked metasurfaces empowered by quasi‐bound states in continuum are reported, order achieve concept hybridized analog computing over both frequency domains. By introducing two types asymmetric degrees, high‐quality resonance symmetry‐protected...
Abstract Reconfigurable optical interfaces with low power cost are of tremendous interest in imaging and communication applications. This work reveals the nonlocal effect twisted electric dipoles demonstrates its capability non‐volatile transformation on scattering. When rotated to form a tilted array, dipolar resonances yield interactions tuned by rotation angle. The collective polarizability maps series circles crossing origin coordinates complex plane, providing 2π phase coverage...
Abstract Metallic nanoshells have emerged as promising optical cavities to steer hybridized plasmonic resonances that show the high spectral tunability and a large surface area of localized fields. Despite various photochemical applications, in shells rarely been explored at low frequencies due nonlinear increase particle size rapid degeneration field localization. Here, this work reports experimental realization plasmon origami metashells can be excited by low‐energy photons ≈7 GHz,...
With the increase of system complexity in wireless communications, higher requirements on miniaturization and integration are put forward for future antennas. Antennas different frequency bands need to be placed together achieve multiple communication goals. However, when a large-sized antenna operating at low-band (LB) is used alongside small-sized high-band (HB), radiation from former can block latter, thereby impacting overall functioning system. In this work, we propose novel method...
In an optical network-on-chip, waveguides play a crucial role in transmitting signals. Therefore, it is essential for to have compact size and low insertion loss. This paper proposes new type of waveguide with vacuum gap based on surface plasmon polaritons. By utilizing polariton technology, the proposed reduces scattering attenuation caused by hybrid polaritons, saves space enables integration more devices chip while maintaining ultracompact requirement. Finite-Difference Time-Domain (FDTD)...
Abstract Evanescent waves, characterized by an exponential decay in propagation, have witnessed significant advancements far‐field imaging and near‐field sensing applications. However, incoming evanescent waves can excite guided resonance inside a dielectric slab, resulting rapid growth of transmission coefficient toward infinity at the pole points. Such evanescent‐wave excited benefits super‐resolution applications yet causes severe crosstalk highly integrated multi‐channel devices. Here,...

We have designed a photoacoustic cell with four resonant cavities the same radius and different lengths, which can achieve two gas differential detection. The crosstalk existed in are analyzed as well.
Traditionally, the performance of a lithography or patterning step is described by its mean size and spread at 3 sigma probability. Recent papers Bristol, Brunner others have shown this insufficient to describe process capability in EUV lithography. To address challenge, an enormous increase sampling CD (critical dimension) values needed actual distribution on wafer. We will show how we can leveraging HMI eP5 e-Beam system acquire set CDs previously unknown size. further that extended leads...
