On-going research topics include...

1. Advanced next-generation antennas

  ○ Advanced reflectarray antennas

     - World's smallest reflectarray antennas (more than 700 times smaller than the latest one)

     - Active electrical beam forming and scanning

     - Remarkably reduce size enough for commercial applications

  ○ Highly efficient Fabry-Perot cavity + artificial reflectors antennas

     - Fabry-Perot cavity antennas consisting of partially reflecting surfaces (PRS)

     - Extremely high aperture efficiency (, which means high gain with reduced physical size..
        It's awesome :)

     - Polarization reconfigurable antennas (horizontal ↔ vertical // linear ↔ circular polarization)

  ○ Mathematical transformation based intuitive antenna design

     - Provides surprisingly new antenna design methodology, which has never been tried 

     - Various shaped antennas can now be designed accurately and precisely

2. Electromagnetic wave manipulation (control)

  ○ Metamaterial & metasurface technology

     - Anomalous refraction, reflection, and transmission techniques

     - Super-directive antenna applications

  ○ Radar cross-section (RCS) modulation technology

     - Smart scatterers for various scattering control

     - Real-time RCS modulation techniques

3. Future-oriented reverberation chambers

  ○ Novel reverberation chamber (RC) technology

     - Rician K-factor control (realization of various wireless communication channels)

     - Miniaturization of conventional RCs

     - Advanced electrical and electronic mode stirring techniques

     - Doppler frequency shift control

     - Q factor control
