An Efficient Model of the Transmission Lines Excited by the External Nonuniform Transient Electromagnetic Field Using the MPM
This letter proposes a modeling approach to handle nonuniform transient electromagnetic field coupling to transmission lines (TLs). In this approach, the matrix pencil method is applied to express the complex-valued external electric field at the horizontal direction along the TL by the first order of the exponential function in the frequency domain. The fitting procedure of the MPM only contains several matrix computation steps and does not need the initial value or any searching process, which leads to a significantly higher fitting efficiency. Moreover, the fitted results are formed with the first order of the exponential function, which ensures that the analytical solution of the TL equation can be formulated and thus has a high calculation efficiency. The proposed method was validated experimentally using a large scale of radiated wave simulator.
期刊介绍：
The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
