We demonstrate the ability to characterize independently the vector components of the electric field associated with terahertz surface plasmons. This is accomplished via electro-optic sampling, using an electro-optic crystal placed in close proximity to a corrugated metal foil. The individual electric field vector components are measured using two separate ZnTe crystals. Since ZnTe exhibits isotropic dielectric properties, all of the detection configurations obey identical phase-matching constraints. Furthermore, since ZnTe is characterized by a single independent electro-optic tensor component, the field measurements may be directly compared against one another.
