  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.
