However, robust unidirectional propagation is achieved exclusively in the ferrite bandgap, where no backward-propagating mode exists. Consequently, robust type-I USMP occurs within the frequency range [0.5ωm, ωm]. The dispersion relation (3) for the type-II waveguide is also depicted in Fig....

The control of optical phase by dielectric metasurfaces is typically realized through dispersion engineering or polarization conversion [9,10,83–90]. In the former case, meta-units are treated as short waveguide segments standing on a substrate. They are designed to possess various cross-sectional...
Figures 7H and 7I depict the simulated near-field electric amplitude for different incident polarization states, which demonstrate the spin-selective properties of the metasurface empowered waveguide.

The control of lights amplitude, phase, and polarisation states through optical devices is a key tool in the modern world for many real-life applications such as sensing [1], imaging [2], and communications. Current optical devices manipulate light via interactions due to their refractive indices...
In recent years, the wavelength-order nanopillar array in Figure 11(f) and the dielectric ridge waveguide made of amorphous silicon have been put forward as phase shift elements. Among these elements, an efficient transmission metasurface can be created at the midinfrared and infrared wavelengths ...
We present a concept of a transparent magnetic metasurface to solve this problem, and demonstrate a novel mechanism for magneto-optical modulation. A 2D array of bismuth-substituted iron-garnet nanopillars on an ultrathin iron-garnet slab forms a metasurface supporting quasi-waveguide mode excitation....
A waveguide with width wa = 1 mm is connected in the middle of the upper boundary. The above six parameters \(\left\{{h}_{r}^{1},{h}_{r}^{2},{h}_{l}^{1},{l}_{r}^{1},{l}_{r}^{2},{l}_{l}^{1}\right\}\) are used as optimization variables for a genetic...
