• response of the entire path (oscillator, waveguide-feeder, lens and the CEB metamaterial itself), with “fingers” due to the used log-periodic antenna of the Josephson oscillator, which was not fully matched to the antenna. Despite this convolution, the experimental data clearly confirm the calculated dual

• the dynamic range and complicating the optimization of noise-equivalent power (NEP). There have been proposals to integrate multiple sensing elements directly into the structure of a log-periodic antenna [28][29][30]. While promising, such designs face significant challenges in implementation. The

• challenging to realize within the constrained geometry of a single-feed log-periodic antenna. Conclusion In this work, we have presented a comprehensive electromagnetic study on the design and optimization of a metamaterial receiver based on split-ring resonators integrated with cold-electron bolometers.
