Signal cross circuit structure and integrated circuit

The invention discloses a signal cross circuit structure and an integrated circuit. A signal cross circuit structure comprises at least two paths of artificial surface plasmon transmission lines which are different in layer and intersect with each other, the intersection included angle is more than 30 degrees, and a dielectric layer is arranged between the adjacent layers of artificial surface plasmon transmission lines. The inventor ingeniously utilizes the characteristic that the artificial surface plasmon has strong constraining force on electromagnetic field energy, so that signal coupling during wiring crossing is weakened, and the purpose that multi-channel signals pass through in a non-influence crossing mode is achieved. Meanwhile, the design principle is simple, professional calculation and design are not needed, and popularization and application are facilitated. And moreover, the requirement on the included angle of the crossed signal paths is very low (greater than or equal to 30 degrees), so that
