Adoption of physical optical theory of diffraction (PTD)

Highly accurate, fast processing PTD method is most ideal for RCS simulation of automobiles, ships, or human bodies.
Because electromagnetic wave dispersion is invisible to the naked eye, the simulation technology has always been the focus in the field. Many techniques such as numerical solutions including the method of moments, physical optics approximation (PO), and the hybrid method that combines the two are being practiced for dispersion evaluation of electromagnetic wave, and among many others, KEYCOM’s PTD-adopted software SFW03, a revision of PO, is highly accurate, fast processing and suitable for large models.

Typical accuracy and calculation time of mathematical simulations
	RCS accuracy (A)	Calculation time (T)	Remarks
Actual Measurement	A		Most accurate, measurement environment dependent
Numerical solution	0.9A	T	Highly accurate but enormous calculation required
Hybrid method	0.5-0.8A	0.1T-0.3T	Most practical, but combination of different methods could cause errors.
Physical optics approximation(PO)	0.3A-0.5A	0.03T	Simple, quick and suitable for large samples.
Physical Theory of Dispersion (PTD)	0.5A-0.7A	0.05T-0.2T	Highly accurate, quick and suitable for large samples.
