Abstract
In this paper, we characterize the dynamics of dissipative discrete breathers (DDBs) in a one-dimensional lattice of two series-connected tunnel diode oscillators. The multistability of the base oscillator is essential for the excitation of the DDBs. We numerically confirm that a largely disordered lattice can support DDBs that are continued from a homogeneous lattice. Based on the predictions obtained from the numerical investigations, the DDBs were successfully observed in the breadboarded test lattice. We also describe the measured DDB properties and examine the lattice with bifurcational analysis. The results suggest that the electrical lattice contributes to the experimental characterization of the autonomously excited DDBs.
