abstract = "We show that accumulation of charges at the metal edges via light-induced currents creates large horizontal electric field, which in effect attracts the incoming light. The enhanced field is fully propagating towards the far-field because no cut-off exists. With the amplitude enhancement in the range of 1,000, the intensity enhancement of 106, and the nonlinear enhancement of 10 12, this structure can be an excellent launching pad for inducing broad-band nonlinearity, small signal detection in astronomy or biology, and for surface enhanced Raman scattering.",
