Mathematical Analysis of Nanostructured Surfaces: The Period-Scale Transform

Figure 2

A rectangular pulse wave with period = 50 and duty cycle (pulse scale) = 20 (a) along with its PST (b). The inset magnifies the transform function at λ = 50 versus scale/width. One can notice the direct way the peaks in PST reveal simultaneously both period and duty cycle (scale) of the analyzed function.
