摘要: Abstract : Wave propagation and random media are defined, the nature of mathematical problems arising in is described. The two principal types methods for solving these problems--honest dishonest methods--are explained. These first illustrated by considering geometrical optics a medium one method each type. Some new results obtained an honest some errors previous work pointed out. Comparison made between reasons why they disagree As second illustration method, analysis reduced wave equation presented. known way which simpler than usual appears to be capable yielding further results.
