Research Interest

Metamaterials - Metamaterials are manmade artificial materials with customisable electromagnetic properties, derived from subwavelength resonant inclusions. With this degree of freedom, they can function to manipulate electromagnetic waves in unconventional ways. My research focuses on metamaterials operating at the microwave and terahertz frequency range with applications ranging from communications to molecular sensing.  Terahertz technology - Terahertz defines a frequency range between 0.1 and 10 THz (THz = 10^12 Hz). This frequency range hosts a variety of microscopic physical phenomena, yet the wave can penetrate most dry, non-metallic substances. My research covers broad aspects of terahertz technology, with particular interests in terahertz components, spectroscopy, metrology, and signal processing. Plasmonics - Plasmonics involves surface waves that are tightly confined onto an interface between a dielectric material and a conductor. These surface waves, also known as surface plasmon polaritons, allows light confinement beyond the diffraction limit with applications in sensing and integrated optics. My research interests span both terahertz and optical plasmonics.  Optical antennas - Inspired by RF antennas, optical antennas function to couple free-space propagating waves with subwavelegnth localised fields at optical frequencies. Their applications include, e.g., intra-/inter-chip communications, beamforming, sensing, wavefront engineering. My interests focus on emerging low-loss optical antennas.
