Abstract :
The high-throughput transmission line matrix (HT-TLM) system is a network-based computational system capable of performing high-performance computing (HPC) of complex electromagnetic structures in grid environments. The high portability and modularity of the system enables distributed full-wave time-domain analysis of 3D electromagnetic structures on heterogeneous systems, platforms and networks. Using the distributed approach of the HT-TLM system, the computation of complex electromagnetic problems requiring large amount of memory and large computational time, may be achieved. The advantages and potentialities in terms of computational time for various platforms and heterogeneous combinations of them are shown by computing the input impedance of a wideband bowtie antenna. To validate the results, the computed input impedance is compared with a method of moments (MoM) solution. To demonstrate the future potentialities of numerical analysis in the grid environments, we make a discussion on applying the hybridization techniques for complex problems.
