Four definitions of magnetic permeability for periodic metamaterials
Skaar, Johannes; Hågenvik, Hans Olaf; Dirdal, Christopher Andrew (Journal article; Peer reviewed, 2019)We state and compare four different definitions of magnetic permeability for periodic, artificial media, or metamaterials. The connections among them, and properties in general, are discussed in detail, including causality, ... -
Higher order multipoles in metamaterial homogenization
Dirdal, Christopher Andres; Hågenvik, Hans Olaf; Haave, Haakon Aamodt; Skaar, Johannes (Journal article; Peer reviewed, 2018)The higher order multipoles above the electric quadrupole are commonly neglected in metamaterial homogenization. We show that they nevertheless can be significant when the second-order spatial dispersive effects, such as ...
