Abstract
This paper presents an active particle designed as a building block of an active volumetric metamaterial showing negative magnetic polarizability. The particle is composed of a conducting ring loaded by an impedance with a negative real part. This impedance is produced by a one-port transistor circuit. The active particle was designed and its stability was discussed. Measurements of the fabricated element verified its working principle in the RF range.
