The properties of GSPs localized at the interface between graphene and conventional materials have been studied theoretically and experimentally [5-10].
However, GSPs propagating along the interface between graphene and metamaterials, such as nonlinear left-handed material, was ignored in previous work.
The line dispersion relation of GSPs can be achieved from literature [6] vvvvv (1) Here c is the speed of light in vacuum, and εi (i=1, 2) are the magnetic permeability and permittivity of the two-side materials surrounding graphene, k denotes the plasmon wave vector normalized to the free light wave number ω∕c.
For example, the characteristic values of the focusing nonlinearity can be estimated for some materials such as n-InSb for which the strength of the critical magnetic field is found as H1 =1.6 A/m.

However, one of the main limitations for the use of wood materials is its flammability.
The lowered flammability of wood materials enables them to be used in high-performance applications, which places emphasis on research into improving their fire retardant properties.
Experimental Materials.
After the main decomposition, mass losses of the residual materials of wood are found to be slow in the temperature range 353–410 °C (the third stage).
