Dr Mitchell Guy Kenney
- Affiliate (School of 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 1,200 citations, and key works include Nature Nanotechnology, Advanced Materials, and ACS Photonics.
Current work involves the design and fabrication of large-area dielectric ultrathin (metasurface) lenses in the NIR, where the largest example in the UK (10 mm diameter) was recently made. This work was present at SPIE - Optical Metrology, Munich 2019, and a link to the Conference Proceedings is given below in "Selected Publications".
His main topics of interest include:
- Perfect Absorbers
- Chiral and fractal devices
