MEMS-tunable dielectric metasurface lens using thin-film PZT for large displacements at low voltages
Christopher A. Dirdal, Paul C. V. Thrane, Firehun T. Dullo +3
Tunable focusing is a desired property in a wide range of optical imaging and sensing technologies but has tended to require bulky components which cannot be integrated on-chip and…

Relaxed dispersion constraints and metamaterial effective parameters with physical meaning for all frequencies
Christopher A. Dirdal, Tarjei Bondevik, Johannes Skaar
Metamaterial effective parameters may exhibit freedom from typical dispersion constraints. For instance, the emergence of a magnetic response in arrays of split-ring resonators for…
