Blow-up solutions of Helmholtz equation for a Kerr slab with a complex linear and nonlinear permittivity. (arXiv:1810.03531v1 [math-ph])
来源于:arXiv
We show that the Helmholtz equation describing the propagation of transverse
electric waves in a Kerr slab with a complex linear permittivity and a complex
Kerr coefficient admits blow-up solutions provided that the real part of the
Kerr coefficient is negative, i.e., the slab is defocusing. This result applies
to homogeneous as well as inhomogeneous Kerr slabs whose linear permittivity
and Kerr coefficient are continuous functions of the transverse coordinate. For
an inhomogeneous Kerr slab, blow-up solutions exist if the real part of Kerr
coefficient is bounded above by a negative number. 查看全文>>
