Patent ID: 8524445

Claim:
A method for establishing a virus spectrum comprising (1) preparing a sample containing a purified known virus; (2) dropping the sample on a coplanar waveguide (CPW) circuit; (3) applying a microwave with frequencies ranging from 40 MHZ to 80 GHZ to the sample on the coplanar waveguide (CPW) circuit; (4) applying a network analyzer with frequencies ran in from 40 MHZ to 65 GHZ to simultaneously record reflection S 11 and transmission S 21 parameters of the CPW circuit; (5) evaluating an insertion power loss by 1−|S 11 | 2 −|S 21 | 2 ; and (6) obtaining an MRA spectrum under a dipolar acoustic mode of the virus by comparing insertion power loss spectra of the sample with and without the virus.
