Abstract: This paper develops a field-circuit co-simulation method to dynamically analyze the space-time coding metasurface arrays. The proposed co-simulation method is to combine discontinuous ...

Introduction: Because it is anticipated to be a new physical quantity for communication multiplexing and has significant potential for increasing channel capacity and enhancing spectrum resource ...

This library implements the finite element method (FEM) for various thermo-piezoelectric systems in Python. The solvers are written using numpy and scipy as well as gmsh for generating 2D meshes. The ...

The true nature of our universe as been an open debate for millennia, and recently, scientists and philosophers have pondered whether it might be a hyper-realistic simulation perpetuated by some super ...

Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to ...

Despite this, tunable metasurface systems often rely on cumbersome or energy-inefficient methods, such as external thermal control. Furthermore, the holographic information contained in metasurfaces ...

Introduction: As an artificial two-dimensional material, metasurfaces are essential for modifying the fundamental characteristics of electromagnetic (EM) waves. Numerous researchers have created and ...

A silicon-lithium niobate metasurface controls light through air at gigahertz speeds, advancing compact systems for optical communication and signal routing. (Nanowerk Spotlight) Optical systems that ...

(Nanowerk Spotlight) Controlling how electromagnetic waves behave as they move through space is essential for technologies like wireless communication, radar, and remote sensing. Engineers have ...
