A variety of structures, methods, systems, and configurations can support plasmons for logic.
1. A method of controlling energy propagation comprising:
guiding energy at a first plasmon frequency along a first path;
blocking the guided energy carried by a guiding structure at the first plasmon frequency from propagating along the first path by resonantly actuating a first portion of the guiding structure along the first path with a first control signal having a first control signal plasmon frequency different from the first plasmon frequency at a first time;
blocking the guided energy at the first plasmon frequency from propagating along the first path responsive to a second control signal, different from the first control signal, at a second time;
receiving an output that is a function of the first control signal and the second control signal; and
guiding energy at a second plasmon frequency along the first path.
2. A method of controlling energy propagation comprising:
guiding energy at a first plasmon frequency along a first path;
blocking the guided energy carried by a guiding structure at the first plasmon frequency from propagating along the first path by resonantly actuating a first portion of the guiding structure along the first path with a first control signal having a first control signal plasmon frequency different from the first plasmon frequency at a first time;

receiving an output that is a function of the first control signal and the second control signal; and
wherein blocking the guided energy carried by the guiding structure at the first plasmon frequency from propagating along the first path includes saturating the first portion of the guiding structure along the first path with the first control signal.
