The Theory of the Iterative Method This method has been introduced firstly as the Fast Wave Concept Iterative Process (FWCIP) in (Azizi et al. 1995) [4], applied since one decade to many kinds of radio frequency integrated circuits and diffraction problems in (N’gongo and Baudrand, 1999)[5].
The (mostly) same method is denoted in literature as Transverse Wave Formulation - TWF (Wane et al. 2005) [6] and more recently Wave Concept Iterative Procedure – WCIP (Baudrand et al. 2007)[7].WCIP compares favorably with other commercially available software regarding the precision and promises better performance in computation efficiency in structures with very different layer heights.

Hot Isostatic Pressing Before HIPing, the decomposition temperatures of the HAp-additive samples were determined (at the maximum fibre addition level) using the methods outlined by Ruys et al [17].
Densification and Decomposition Behaviour After HIPing, the decomposition effects (%HAp yield) and bulk density of the samples were measured according to the methods described by Ruys et al [44].
