Title Research on electromagnetic distribution characteristics of Nano antenna scale array
Abstract Antenna has been widely used in the field of microwave, but the light is also a kind of electromagnetic wave, the electromagnetic distribution of the Nano antenna and microwave have similar characteristics。 To study this kind of characteristic, it is helpful to study the use of optical antenna in optics, such as high efficiency solar cells, optical microscope, can raise the utilization rate of light and so on。
This paper mainly studies the theory of the microwave, some indicators of the antenna to solve, and then make the antenna model, simulation and comparison, preliminary electromagnetic distribution characteristics, the main work of this paper is as follows:
(1)by using some theories of microwave, the basic principle of finite element, the scattering problem of three-dimensional medium and the equation of surface integral and MLFMA, the calculation method is realized on the Nano antenna;
(2)using HFSS to simulate the Nano antenna model, and then change the properties of the antenna, draw the difference of the changes, and then preliminary discussion of the electromagnetic characteristics of the Nano antenna;
(3)summary of the above simulation, explore nano antenna element size, element spacing, shape, material, the number of nano antenna electromagnetic distribution characteristics influence, and provide a direction for the optimization design of the future
Keywords : Nanometer grade Principle of finite element PMCHWT
