Strongly Enhanced Sensitivity in Planar Microwave Sensors Based on Metamaterial coupling

open access: yes, 2017
Limited sensitivity and sensing range are arguably the greatest challenges in microwave sensor design. Recent attempts to improve these properties have relied on metamaterial- (MTM-) inspired open-loop resonators (OLRs) coupled to transmission lines (TLs)

Multipole nonlinearity of metamaterials

open access: yes, 2009
We report on the linear and nonlinear optical response of metamaterials evoked by first and second order multipoles. The analytical ground on which our approach bases permits for new insights into the functionality of metamaterials.
