Prof. Lim Sung-jun and Saptarshi Ghosh–a postdoctoral researcherof the School of Electrical & Electronics Engineering, Chung-Ang University (CAU) received the best paper award at 2018 International Symposium on Antennas and Propagation (ISAP), held in Busan, Korea.

 

Prof. Lim and Ghosh conducted research on electromagnetic wave absorber using 3D printing technology and published a research paper, entitled “Lightweight 3D Printed Metamaterial for Electromagnetic Wave Absorption.” They discovered that, with the application of 3D printing to metamaterials, it is possible to not only arbitrarily process the electromagnetic properties of materials, but reduce the weight of materials considerably.

 

Metamaterials, an artificial substance engineered to have unnatural properties, are generally known to be produced by a printed circuit board. Once the electromagnetic properties of metamaterials are processed, they can display a negative refractive index and create an invisibility cloak. In addition, development of an electromagnetic wave absorber will lead to producing a stealth aircraft, designed to evade the enemy’s radar. This research result gains much attention from the scientific community in the sense that both stealth properties and flight performance of fighter jets can be further strengthened with the use of lightweight electromagnetic wave absorbers.

 

In the meantime, the research lab, led by Prof. Lim Sung-jun, adopts metamaterials and new materials to build a better wireless and propagation environments. On top of this, the research lab focuses on applying their research results to a variety of areas such as stealth, 5G mobile telecommunications, and wireless electromagnetic sensor technologies.
