- Building the physics background and technology to research perfect absorbers based on metamaterials operating in the radar wave region from 2 to 18 GHz.
- Applying technology process to fabricate the perfect absorbers in the radar wave region. The perfect absorbers are measured in the electromagnetic region with the frequency ranging from 2 to 18 GHz.

a. In scientific and technological fields:
- Successfully built the fabricating equipments system and technology process of metamaterials perfect absorbers (A ~ 100%) with no reflection of radar wave operating in different desired frequency regions between 2 and 18 GHz. Equipments system has high precision, the resolution of ± 0.01 mm, and highly reiterative fabricating technology process.
- Successfully designed, simulated and fabricated MPAs with different structures: split-ring resonator, I shape, cut-wire, cross shape, flower shape, disk and ring.
- Researched the influence of structural geometry on the absorption property of materials. Results show that the interaction between electromagnetic wave and MPAs with different structures exhibits different properties. The absorbance of the I shaped absorber is nearly 100% at 14.3 GHz, while the cut-wire absorber exhibits the absorbance of nearly 100% at 15.6 GHz. Nevertheless, both of these structures are strongly dependent on the polarization angle of the incident electromagnetic wave.
- Researched the influence of structural parameters on absorption property of MPAs with different structures. Results prove that the structural parameters are strongly influential in absorption property of materials.
- Designed and fabricated multi-peak absorber at different separate frequencies by combining many disks with different sizes in a unit cell. In addition, project designed broadband MPA with the absorbance above 80% in the bandwidth of 2.5 GHz.
