Experiment on Lattice Soliton by Nonlinear LC Circuit—Energy of Soliton

Abstract

We have experimentally investigated the energy of soliton in a nonlinear transmission line which is equivalent to the Toda lattice. In the nonlinear circuit, the magnetic and electric energies are not equal with each other. The present experiment shows that the magnetic energy of a soliton is superior in quantity to the electric one, in agreement with theory. This corresponds to the fact that the kinetic energy is larger than the potential energy in a lattice soliton. It is also confirmed experimentally that the magnetic energy is converted to the electric energy at the instant of a head-on collision between two solitons. Such an energy exchange is not observed for an overtaking collision of two solitons.
