• First textbook dealing with crystallography of incommensurately modulated crystals and incommensurate composite crystals.
• Provides a comprehensive account of the superspace theory - necessary background for the understanding of incommensurability in crystal structures.
• Includes a complete account of crystallographic methods of structural analysis of incommensurate crystals.
• Important applications in the study of materials like high-temperature superconductors, low-dimensional electronic crystals, charge-density wave compounds, magnetic materials and ferroelectrics.

Readership: Graduate and postgraduate students, and researchers working in crystallography and solid state chemistry.

"Good and timely. " - Marjorie Senechal, Department of Mathematics and Science and Technology, Smith College, USA

"There is a need for a self-contained book on the structure analysis of incommensurate crystals. Potential readers of such a book would be all who are involved in structure analysis of aperiodic crystals plus solid state chemists and physicists." - Walter Steurer, Laboratory of Crystallography, ETH Zurich
