Abstract: The present invention discloses microwave resonant absorption (MRA) of viruses through dipolar coupling to viral confined acoustic modes. The unique geometrical and mechanical properties of viruses can be reflected by the MRA frequencies, MRA linewidth, and the absorption selection rules of high-order acoustic modes. Combined these spectral characteristics with the mature microwave technology, this invention provides a novel physical mechanism to develop non-affinity-based rapid detection and identification of viruses. It can be applied in preliminary characterization on unknown or mutant viruses.
