One key difficulty in realizing Majorana zero modes (MZMs) is the required high magnetic
field, which causes serious issues, eg, shrinks the superconducting gap, reduces topological …

Bound states in the continuum (BICs) are zero-width (infinite lifetime) trapped eigenmodes
that remain confined in the system even though they coexist with a continuum of extended …

The confinement of waves in open systems represents a fundamental phenomenon
extensively explored across various branches of wave physics. Recently, significant …

Photonic biosensors based on bound states in the continuum (BIC) resonant modes exhibit
a transformative potential for high-sensitivity, label-free detection across various diagnostic …

Herein, we achieve giant Goos-Hänchen (GH) shifts driven by Fabry-Perot quasibound
states in the continuum (quasi-BICs) in double-layer gratings. Based on the hybrid coupling …

Modes with a high-Q factor are crucial for photonic metadevices with advanced
functionalities. In sharp contrast to recent techniques which generate a supercavity mode by …

A wavy dielectric grating hosts bound states in the continuum (BICs) at nonzero Bloch wave
number. For an oblique incident optical field with parameters near to the BICs, the …

Periodical corrugation in the dielectric slab transforms the two waveguide modes at zero
Bloch wave number into a leaky resonant mode and symmetry-protected bound states in the …

We propose a double-layer high-contrast metagrating structure with robust high-quality (Q)
and temperature self-compensation for four-band refractive index sensing. The structure …
