Abstract :
It is known that the fields present on an open periodic structure can be expressed as an infinite sum of space harmonics, and that each of these space harmonics which is a fast wave along the surface corresponds to a radiating beam. The radiation characteristics can be conveniently represented in the form of a k vs. B diagram, or dispersion curve, on which radiation generally occurs when the operating point is located outside of a set of specified triangles.
