This paper proposes a new negative impedance converter (NIC) with an emitter follower (EF) circuit. Two types of NICs with EF and without EF, designed to generate a negative capacitance of -100 pF, ...

Periodic arrays of shunted piezoelectric patches are employed to control the propagation of elastic waves in phononic beams. Each piezo-patch is connected to a single resistance-inductance-negative ...
