HIGHLIGHTS
- who: Gradient Impedance Graphene Films. and colleagues from the National Key Laboratory of Antennas and Microwave Technology, Xidian University, Xi`an, China have published the Article: An Ultra-Broadband and Highly-Efficient Metamaterial Absorber with Stand-Up Gradient Impedance Graphene Films, in the Journal: Materials 2023, 16, 1617. of /2023/
- what: In this paper an ultra-broadband and highly-efficient MMA is presented. If the authors focus on the amplitude of the electrical field at the positions of antinodes labelled with red and gray dashed boxes, the authors will find that the electrical field amplitude . . .
