Power and spectral characterization of photonic integrated circuit based axicon like lens
Rijan Maharjan, Sanket Bohora, Pravin Bhattarai +5
We demonstrate an on-chip Silicon-on-Insulator (SOI) axicon etched using a low resolution (200 nm feature size, 250 nm gap) deep-ultraviolet lithographic fabrication. The axicon co…

Intermittent dilation and its coupling to stress in discontinuous shear thickening suspensions
Rijan Maharjan, Ethan O'Reilly, Thomas Postiglione +2
We investigate dilation-induced surface deformations in a Discontinuous Shear Thickening (DST) suspension to determine the relationship between dilation and stresses in DST. Video…

An effective packing fraction for better resolution near the critical point of shear thickening suspensions
Rijan Maharjan, Eric Brown
We present a technique for obtaining an effective packing fraction for discontinuous shear thickening suspensions near a critical point. It uses a measurable quantity that diverges…
