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, they are not coupled to the latter ...

Total reflection X-ray fluorescence (TXRF) is an advanced spectroscopic method for multi-element detection at trace and ultra-trace levels. By directing a monochromatic X-ray beam at a sample ...

TIRFM is a sophisticated fluorescent microscope that allows a user to visualize a very small region of a specimen. TIRFM utilizes optics to produce light at the interface of the slide. This technique ...

(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 ...
