Advanced Science, EarlyView.A compact eight‐channel electrically tunable varifocal metalens with three single‐layer polarization‐multiplexed bi‐focal metalens and three LC cells. The total thickness of the device is ∼6 mm, while the focal lengths can be switched among eight values (3.6, 4.2, 4.5, 4.9, 6.2, 6.9, 8.4, and 9.6 mm). ABSTRACT As an essential module of optical systems,

The inclusion of fringing capacitance and inductance in FDTD for the robust accurate treatment of material discontinuities [PDF]
, 2000 The analysis of structures, which contain sharp material discontinuities using the finite-difference time domain method (but without resorting to a very fine mesh) although much researched, has not yet been definitively solved.

Advanced Science, EarlyView.A layered bead‐network wallpaper is designed to modulate the light propagation path, overcoming the color residue limitations of thermochromic components for efficient automatic switching between radiative cooling and solar heating modes. The layered bead‐network wallpaper provides passive, all‐season thermal regulation while offering self‐cleaning and

Calculation of losses in 2-D photonic crystal membrane waveguides using the 3-D FDTD method [PDF]
, 2004 The three-dimensional finite-difference time-domain method is used to obtain loss per unit length in a two-dimensional photonic crystal membrane waveguide by simulating three different length guides. Results are shown for propagation both above and below
