Nonlinear NRCH model

To build our theoretical framework, we start with the dynamics of conserved fields ϕ_i (i = 1, 2) that can be written as \({\dot{\phi }}_{i}={\Gamma }_{i}{{{\boldsymbol{\nabla }}}}^{2}{\mu }_{i}\), in terms of the scalar…

The device, depicted in Fig. 1a, comprises two misaligned photonic crystal slabs stacked in free space. These two crystals comprise of a stack of 1D gratings. This configuration allows for a tunable diffraction pattern with the misalignment…

Hydrodynamic linear response of hybrid heavily doped semiconductor waveguides

From a theoretical perspective, LBP resonances can be excited in finite-size systems if the material response is nonlocal^39,45. One way to account for nonlocality in…
