GL EM Mechanical and Acoustic Field Time Domain Modeling for Materials and Ezploration with Dispersion
In last few years, we proposed Global and Local field (GL) electromagnetic (EM), elastic and other field modeling in the frequency domain. In this paper, we propose GL model-ing for EM, mechanical, and acoustic field in aperiodic space time domain and dispersion field in periodic space time domain. First, we derive magnetic, electric, elastic, and acoustic field differential integral equation in aperiodic and periodic space time domain. Based on these dif-ferential integral equations, we construct GL EM, mechanical, and acoustic field time domain modeling in aperiodic and periodic space domain. The EM field and mechanical field is different field in physical theory and application. However, they have some important relationship in the mathematical physical research and applications. In the macro scope and macro to micro mixed scope the coupled EM and mechanical field play important role. Our GL method can be used for EM, mechanic, acoustic, flow, quantum mechanics and their mixed coupled field modeling, in particular, for EM dispersion in photonic crystal, elastic dispersion in special rock, flow disper-sion in pores media and other mixed periodic and aperiodic optical materials. The time domain GL method does not need to solve any large matrix, only 3×3 and 6×6 matrices needs to be solved. Moreover, the artificial boundary and absorption condition are unnecessary in the time domain GL method. Some applications in material science, dispersion of photonic crystal and exploration are described in this paper.
