Design and study of a coronavirus-shaped metamaterial sensor stimulated by electromagnetic waves for rapid diagnosis of covid-19

We propose a new technique of utilizing metamaterials-based sensor for rapid diagnosis of covid-19 through electromagnetic-stimulated analysis of the blood drawn from the patient. The sensor was inspired by a coronavirus in plane-shaped design with presume that its circular structure might produce a broader interaction of the electromagnetic waves with the blood sample. The sensor was designed numerically and tested experimentally by evaluating variations in the reflection coefficient (S11) and transmission coefficient (S21) of the waves at resonant frequency. Results of covid-19 relevant blood sample showed a pronounced shift in the main resonant frequency of about 740 MHz compared to that of the control blood sample. We believe that with the help of the proposed sensor a significant breakthrough can be achieved for rapid diagnosis of covid-19 within few seconds.
