Abstract: The rigorous diffraction boundary problem for a semitransparent slotted semi-infinite cone is considered. Slots are periodically cut along its generatrices from the cone tip. The source ...

Scientists from the UK and China have developed a lateral-graded multilayer grating that addresses a key challenge in tender X-ray RIXS technique. Demonstrated at the I21 beamline in Diamond Light ...

Abstract: We demonstrate a chip-scale spectrometer based on subwavelength grating microring resonators, achieving a bandwidth of 114 nm and a resolution of 40 pm. Using a spectral reconstruction ...
