  In this work we study the energy transport in a one-dimensional system
composed of two dissimilar Frenkel-Kontorova lattices connected by a
time-modulated coupling and in contact with two heat reservoirs operating at
different temperature by means of molecular dynamics simulations. There is a
value of the driving frequency at which the heat flux takes its maximum value,
a phenomenon termed as thermal resonance. Structural modifications in the
lattice strongly alter the way in which the external driving interacts with the
phonon bands. The overlap of the latter in the harmonic regime of the model
determine the frequency range wherein resonance emerges. Parameter dependencies
by which the incoming heat flux can be directed to either of the heat
reservoirs are examined as well. Our results may be conductive to further
developments in designing thermal devices.
