Matlab Simulation of Electromagnetic Waves Propagation Characteristics

摘要

Military technology has developed rapidly in recent years and used widely in marine communications,maritime aviation,and underwater exploration.With the rapid development of signal processing and antenna technologies,underwater electromagnetic communication has received much attention.Since water is a conductive medium,characteristics exhibited by electromagnetic waves in water are fundamentally different from those in oil.In order to better study the propagation characteristics of electromagnetic waves within the medium,the simulation of the electromagnetic wave propagation in water and oil were conducted using MATLAB,and variation of the electric field and magnetic field vector with time were obtained.Moreover,the three-dimensional real-time graphics of electromagnetic wave propagation can also be simulated in MATLAB;different patterns of electromagnetic waves propagating in oil and water were generated.
