The transmission line transfer matrix method (TLTMM) is presented for the analysis of multilayer electric structures as frequency selective surfaces (FSS), whereby the reflection, transmission and absorption coefficients, field distribution and power flow may be computed inside and outside of the layers. The TLTMM formulation may be developed for any arbitrary angle of incidence, any polarizati...

This paper presents a 3D transmission line matrix (TLM) implementation for the solution of transient heat flow in power devices. The miniaturization of electronic networks creates problems of heat dissipation. Good thermal management is therefore essential. Simulating power electronic systems presents peculiar challenges due to the need of detailed modeling of both circuitry and control algorit...

This letter sets out to describe the first results of design process that will lead a new on-line partial discharge location method based on Electromagnetic Time Reversal theory and using Transmission Line-Matrix method. A description basic steps under is given together with modeling procedure used time inverted signal propagation. Finally, ability locate discharges power cables both two observ...

In this paper a transformerless Static Synchronous Series Compensator (SSSC) to increase the power capacity of a 230 kV transmission line is proposed. In order to eliminate the transformer, a 15-level cascade H Bridge (CHB) inverter is employed within the proposed compensator structure to inject reactive power to the transmission line. The theory of instantaneous p-q power using in the compensa...

This paper describes progress on the TLM modelling of the Laplace equation, in particular, how the rate of convergence is influenced by the choice of scattering parameter for a particular discretisation. The hypothesis that optimum convergence is achieved when the real and imaginary parts for the lowest harmonic in a Fourier solution cancel appears to be upheld. The Fourier solution for the pro...

A new approach for time-domain analysis and design of lumped networks is considered. The lumped elements are modeled by transmission-line sections or stubs and the modeled network is analysed by the transmission-line matrix (TLM) method, which provides an exact solution to the model. Compensafion of errors arising in modeling the network elements is discussed. Sensitivities w.r.t. design variab...
