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 ...

A TIR lens is an optical lens built on the principal of total internal reflection (TIR). TIR lenses collimate light, sending out a concentrated beam of full intensity. They are used in a wide variety ...
