Wenqi Zhu

Wenqi Zhu is a PML/UMD Postdoctoral Researcher in Microsystems and Nanotechnology Division. He received a B.S. in Electronics Engineering from Tsinghua University, China and a Ph. D. in Engineering Sciences from Harvard. His doctoral research focused on fabricating and characterizing plasmonic optical antennas for use in surface-enhanced Raman scattering. He also has expertise in fabricating terahertz metamaterials and waveguides. Wenqi is working with Henri Lezec on numerically simulating, designing, fabricating, and experimentally characterizing advanced plasmonic devices and metamaterials operating at infrared, visible, and ultraviolet frequencies.
