Methods of the theory of the electromagnetic field in micro-optics
7.1 Analysis of the DOE by the method of finite-difference time-domain solution of Maxwell equations
Chapter 1 dealt with the Maxwell equations in the differential form (section 1.1.2) and with the finite-difference method of solving the differential equations (section 1.5.1). This chapter is concerned with the application of this method for solving these equations.
The approaches developing the concept of the fundamental study  will be discussed. In particular, a method of transition to the frequency range (when investigating the diffraction of monochromatic light) and another method of formulating the incident wave source condition which is simpler than the method described ...
