Optimized cross-polarized LEKIDs for W-band using sawtooth inductors

Lumped-element kinetic inductance detectors (LEKIDs) based on sawtooth inductors for W -band are presented in this article. A careful analysis is carried out for the cross-polarization in the inductor geometry, which brings out the absorption of the nondesired E -field component of an incident wave...
