Bound states in the continuum (BICs) are a special class of resonant states. Although they have the same momentum and energy as the propagating modes in free space, yet they are not coupled to the ...

(a) Total internal reflection of two Bloch waves at the interface of the photonic crystal. (b) Guidance condition: as a Bloch wave reflects twice, it duplicates itself. (c) Conventional and ...

Seismic oceanography has emerged as a transformative methodology that employs seismic reflection techniques to image the intricate internal structure of the ocean. By capitalising on high‐resolution ...
