Abstract
MATLAB is a suitable for many professional discipline, a variety of task performance of pow
erful visualization computing software platform, with all kinds of library functions, toolbox a
nd simulation application module. Can refer to the MATLAB to scientific research and proces
sing all kinds of engineering design and practical problems. Therefore, we in the electromagn
etic field is used to solve the problem, can with the aid of MATLAB powerful development e
nvironment and interactive tools for solving electromagnetic field problems, and can map out
metal waveguide device in all kinds of mode of transmission of electromagnetic field distribut
ion.
On cross section perpendicular to the electromagnetic wave transmission the purpose of, there
are differences in the form of electromagnetic wave with various mode field distribution diag
ram, each field distribution is a kind of form, such as rectangular, circular wave guide device
can transmit in the different forms of electromagnetic wave, I with the aid of MATLAB to stu
dy, because the MATLAB has applied to different subjects, powerful visualization computing
software, have different amounts of library functions, toolbox and simulation application mo
dule. Can use MALTAB, the partial differential equation is used to solve the toolbox and asse
mbly process to solve the actual problem of answer, and draw different patterns of electromag
netic waves.
Therefore, in the electromagnetic field numerical and graphical solution, we can refer to the d
esign of control system and MATLAB simulation and drawing function to engineering and sc
ience research metal waveguide devices in different mode field distribution of guided wave tr
ansmission. So, graphics simple, can strengthen our understanding of metal waveguide device
and practical application.
