| Research Abstract |
Transmissions of information or energy can be performed by use of the wave propagation phenomena. In this study we treated the information transmission by spoken language and electromagnetic radiation with various frequencies from antennas. We developed the methods to reduce the problem in unbounded region into the one in a bounded region using two techniques and then discretized the problems by FEM or FDM. We also developed similar methods for energy propagation phenomena such as those in elasticity or in electromagnetism and applied the method to several problems in seismology or electromagnetic wave heating phenomena in MRI.
