Intrinsic localized modes (ILMs) have
been generated and characterized in two-dimensional
nonlinear electrical lattices which were driven by a
spatially-uniform voltage signal. These ILMs were
found to be either stationary or mobile, depending on
the details of the lattice unit-cell, as had already been
reported in one-dimensional lattices; however, the mo-
tion of these ILMs is qualitatively di erent in that it
lacks a consistent direction. Furthermore, the hop-
ping speed seems to be somewhat reduced in two di-
mensions due to an enhanced Peierls-Nabarro (PN)-
barrier. We investigate both square and honeycomb
lattices composed of 6
x
6 elements. These direct ob-
servations were further supported by numerical simu-
lations based on realistic models of circuit components.
The numerical study moreover allowed for an analysis
of ILM dynamics and pattern formation for larger lat-
tice sizes
