The basic analytic method and phenomena of electromagnetic interference is explained through the discussions of Young s experiment of polarized light within the framework of fundamental optics based on the superposition of vectorial waves,including the interference of two linearly polarized beams and the case of one linear beam passing through a pair of wave plates of arbitrary thickness.

Reinvestigation of the theorem of quasi-phase-matching with the method of vector superposing;

The proposed approach can offer an exact solution for dynamic response of base-isolated structure,through using the complex mode superposition method.

A combined wave superposition method is proposed to transform near-field acoustic holography.

An acoustic theoretical model for extracting mechanical fault features and the wave superposition method were proposed to reconstruct the acoustic fields generated by arbitrarily-shaped radiators in order to compute the number and location of noise sources.

By virtue of the comparability between the wave superposition method and the dynamic analysis of structures, a general format to overcome the non-uniqueness of solution induced by the wave superposition method at the eigenfrequencies of the corresponding interior problems is proposed in this paper.
