Understand the physics behind total internal reflection and why light can become completely trapped inside a medium. This video explains the conditions required for total internal reflection, the role ...

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 ...

Compared to through-hole construction, inspecting SMD construction is a whole other game. Things you thought were small before are almost invisible now, and making sure solder got where it’s supposed ...

(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 ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
