Investigation on the Crack Effect in the Cylinder and Matrix on the Backscattering Field Frequency Specifications using the Finite Element Method [PDF]
Journal of Applied and Computational Mechanics, 2022 A novel method to determine the health of the industrial parts is using the ultrasound scattering waves. Any changes in the structure of the scattering object or in the boundary conditions will cause a change in the scattering field.

Effects of Nanocylinders on the Whispering Gallery Modes in a Microcylinder. [PDF]
Sensors (Basel), 2016 Optical biosensors have been studied extensively for the detection and characterization of biological entities, such as viruses, bacteria, and biomolecules. A two-dimensional (2D) microcylinder resonator ( Q ∼ 2 × 10 5 ) was designed, and the effects of a nanocylinder on the whispering gallery modes (WGMs) were examined numerically.

Reconfigurable Liquid Whispering Gallery Mode Microlasers [PDF]
Scientific Reports, 2016 AbstractEngineering photonic devices from liquid has been emerging as a fascinating research avenue. Reconfigurably tuning liquid optical micro-devices are highly desirable but remain extremely challenging because of the fluidic nature. In this article we demonstrate an all-liquid tunable whispering gallery mode microlaser floating on a liquid surface ...
