What's New

  • (Mar 6, 2017) I participated in designing a ultrathin, subwavelength spectral light separator. This image sensor device captures three different wavelengths within a 50nm-thick pixel efficiently over a wide range of incidence angles.

  • (Oct 25, 2016) I co-developed a new computational electromagnetics method for simulating multi-time-scale phenomena. To simulate phenomena involving vastly different frequencies (e.g., GHz modulation of THz signals), time-domain methods require a huge number of time steps (to simulate slow frequencies) with very fine step size (to resolve fast frequencies), so they take very long simulation time. On the other hand, conventiontal frequency-domain methods find the steady-state solution directly, but they can handle only one frequency at a time. Our new frequency-domain method is able to find the steady-state solution involving multiple frequencies, so it overcomes the limitations of both the conventional time- and frequency-domain methods.

  • (Jun 21, 2016) I helped designing microfluidic channels with optical trap-and-release mechanism.

  • (Oct 26, 2015) My detailed analysis of the behavior of the Ohmic loss rates in metallic slot waveguides is published. The analysis reveals that the Ohmic loss rates of microwave signals are plateaued at a material- and shape-independent value before reaching the theoretical maximum typically attainable by optical signals. The plateau explains why microwave signals have negligible Ohmic loss compared to optical signals.

  • (Sep 01, 2015) I start as an Applied Mathematics Instructor and Postdoctoral Associate at MIT.
