Comments on “The Gilbert–Holland FDTD Thin Slot Model Revisited: An Alternative Expression for the In-Cell Capacitance”

The supposed inaccuracy found by the authors of

when using the results of

stems from a misapplication of the referenced equation. The authors of

neglect to include the effective permeability of the slot in their simulation of a finite thin slot in a three dimensional scattering simulation. Furthermore it is pointed out that the authors'
Fig. 3
is a physical impossibility.
