Dr Mitchell Guy Kenney
- Research Associate (Electronic & Nanoscale Engineering)
Mitchell Kenney received his M.Sci. in Physics & Nanotechnology at The University of Birmingham in 2011, continuing on to do his Ph.D. with Professor Shuang Zhang in the Metamaterials Research Group, graduating in July 2016.
Previous research includes the investigation of plasmonic, metallic and dielectric metasurfaces for manipulating the wavefront of light, with a key interest in Pancharatnam-Berry phase. He has over 500 citations, and key works include Nature Nanotechnology, Advanced Materials, and ACS Photonics.
His main topics of interest include:
- Perfect Absorbers
- Chiral and fractal devices
