This book contains all the information about a coherent control of the lateral shift or Goos-Hanchen shift. The coherent control of the Goos-Ha?nchen shift has been investigated when a probe light is incident on a cavity which contains dispersive atomic medium. We consider different atom-field configurations for the intracavity atomic medium, i.e....

Poly gamma glutamic acid (PGGA) is a HPA (homo polyamide) occurring naturally. It is made of D and L form of glutamic acid units which are typically connected by the amide linkages between the alpha-amino group and the gamma-carboxyl group as shown in the figure 4.1.Thus, it has resistance against the protein breaking enzymes known as proteases....
