Design of an Al microwave superconducting resonator for 2 mm wavelength detection

In this work, we present the design of a LEKID aluminum pixel that potentially can be used as part of a detector array on a millimeter wavelength system detection to be installed on a millimeter wavelength telescope. The LEKID pixel is designed to work at 250 mK bath temperature, simulations of the optical coupling show that detector absorb EM radiation within of the 2-mm wavelength atmospheric window and electrical simulations allowed to determinate the electrical parameters such as the resonant frequency, f
_r
=2.152 GHz and resonator quality factor, Q
_L
=50000. The noise equivalent power calculated for this LEKID is ~3.51×10

W/√Hz allowing 2 mm wavelength ground-based observations.
