Control Electromagnetic Field

We study the controlling electromagnetic applications in engineering electromagnetic from two aspects.First.a method based on T-matrix and boundary integral equation is used to realize the illusions of electromagnetic target. Second,based on coupled mode theory,we design a new type microwave resonant cavity structure for microwave UV curing equipment.In recent years,electromagnetic invisibility cloak and illusion has become one of the most hot points for researching in science and engineering.The main research contents of illusion of electromagnetic target are cloaking,switch and shift.T-matrix and boundary integral equation is effective way to design active device cloak and realize electromagnetic illusions. We do research about active device cloak based on above theory. Presents the design method of active device cloak and form the scattering formulas of perfect metal cylinder,metal cylinder with both wings,and arbitary object. We design three kinds of active device cloak model.and do the simulations in MATLAB. Realized electromagnetic target illusions of some classical objects and electromagnetic target shift of perfect metal cylinder.based on active device cloak models. To check the reliability of active device cloak,designed a group of formulas to calculate the precision.The active device models have extremely high precision through the calculations. This thesis provides a new thinking to design active cloak mode and realize the illusions of electromagnetic target and expands the cloak research.Microwave UV curing technology is widely used in micro-electronics,biological engineering, industrial production and other fields. Refer to the principle of traditional UV curing equipment, we design a new type of microwave radiation system. We design the resonant cavity and lampshade in HFSS,and get the electromagnetic field and reflection coefficient of wave port through simulations. Through the actual processing and test,we successfully brighten up the electroless lamps.So we acquire important foundation for the future work.
