Dynamic materials (DM) comprise spatial material frameworks and their energetic interactions with the environment responsible for temporal changes in material properties. This paper studies a checkerboard pattern of variable electrical material properties in space-time. Impedance mismatch causes reflection of energy which one would expect to slow energy accumulation, but this does not happen; this paper explores why. Impedance mismatch was found to produce energy accumulation effects separate from those of velocity mismatch. In most of the simulations, these effects more than make up for the losses from reflection out of limit cycles, but some of the simulations suggest parameters exist for which energy loss may occur.
