IT is generally accepted that the low-angle X-ray diffraction pattern of collagen is unidimensional in the direction of the fibre axis with a fundamental period of 640 A. 1. Variations in the ...

Diffraction gratings have been widely used in wavelength-controlled nonmechanical laser beam steering for high data-rate indoor optical wireless communications. Existing free-space diffraction ...

A rigorous coupled-wave model is proposed to simulate the diffraction characteristics of a concentric circular metal grating (CCMG) for an incident transverse-magnetic (TM) wave at terahertz frequency ...

3. The “Curved” Coupled Wave Theory Based on “Plane” Coupled Wave Theory In the last section, the interference fringes are formed by the signal beam and the reference beam in the holographic material, ...

This is a calculus-based textbook on general physics. It contains all the major subjects covered in an intermediate or advanced course on general physics. It also embraces the most recent developments ...
