A metasurface is an artificial structure that reflects electromagnetic waves in a different direction than normal.
A next-generation material that has the potential to become the basic infrastructure for Beyond 5G communications.
A new patterning method that combines the plating primer “Metalloid” and exposure technology was used to create metasurface samples and evaluate their performance.
Fabrication process of metasurface film
1. Coating a plating primer (metalloid) onto a 100 µm thick PET film
2. Photo-patterning with ultraviolet light at a wavelength of 365 nm using a film mask
3. Electroless Cu plating (thickness 1 µm)
Appearance of metasurface film
Evaluation of metasurface film
No peeling in tape peeling test (JIS H 8504)
The interface between the substrate and the plating film is smooth
