Equivalent circuit modeling of the dielectric loaded microwave biosensor

This article describes the modeling of biological tissues at microwave frequency using equivalent lumped elements. A biosensor based on microstrip ring resonator (MRR), that has been utilized previously for meat quality evaluation is used for this purpose. For the first time, the ring-resonator load...
