Metasurface has demonstrated potential and novel optical properties in previous research. The prevailing method of designing a macroscale metasurface is based on the local periodic approximation. Such a method relies on the pre-calculated data librar

For passive dielectric waveguide devices, we are primary concerned with their steady-state behaviors or narrow-band characteristics. Hence the frequency-domain (FD) methods, such FD finite-difference (FD-FD) methods are often used for solvin

Wide-angle optical systems play a vital role in imaging applications and have been researched for many years. In traditional lenses, attaining a wide field of view (FOV) by using a single optical component is difficult because these lenses have cruci

Focus-tunable lenses are indispensable to optical systems. This paper proposes an electrically modulated varifocal metalens combined with twisted nematic liquid crystals. In our design, a metalens is employed to focus on different points depending on

We present a high-order accuracy compact transparent boundary condition (TBC) for the Helmholtz equation. These TBC coefficients are derived from the principle of local plane wave extrapolation (LPWE). LPWE is when an EM field at a given point on the

This paper investigates the voltage hysteresis effect and residual birefringence in the polymer-stabilized blue phase I and II, under various phase separation conditions. By irradiating samples with ultraviolet (UV) light and curing the samples at a
