Interference Metallurgy

Generally, patterning techniques can be basically divided into two groups  

The simplest form of fight is a monochromatic, finear polarized plane wave. This is a sufficient approximation of areal laser beam. Under the assumption ofplane waves, the total field E) of the interference pattern can be obtained by adding all the individual j beams  

The product between k and r can be written in terms of aj and Pj which are the angles between the beams with respect to the interference plane (Fig. 1) 

The two-beam interference (n = 2) produces a linear pattern. Assuming that 

The calculated line-type interference pattern is shown in Fig. 2(a). The period of the structure (P) is given by

The third section has three chapters. Chapter 10 analyzes the Laser Interference Metallurgy which allows the creation of periodic patterns with a well-defined long-range order at the scale of typical microstructures (from the sub micrometer level up to micrometers). Chapter 11 discusses general phenomena involved in electrodeposition process, commonly used techniques and application of electrodeposition in different areas of research and industry. Lastly, Chap. 12 describes the plasma state and its application to modify surfaces in order to obtain a desired functional property in the biomedical field.
