Tunable Epsilon Near Zero Metamaterial with Rotating Obround-Shaped Meta-Atoms
Rustam Balafendiev, Gagandeep Kaur, Jim A. Enriquez +4
A new design of a microwave-range ENZ metamaterial consisting of rods with an obround cross-section is proposed. The plasma frequency of the metamaterial can be tuned by rotating t…
