Mobile computing devices are ubiquitous and can now carry out computationally-intensive tasks in a timely fashion. This paper presents multi-platform, computational electromagnetics educational software for modern mobile platforms. Performance of the Transmission Line Matrix (TLM) solver has been increased using a Single Instruction, Multiple Data (SIMD) processing strategy applicable to the majority...
A Discrete Random Variable for Raindrop Wave Propagation Modelling. This presentation describes a technique for generating a discrete random variable (DRV) for raindrop diameter when using a raindrop geometry model that is not continuous in nature. This can be applied to high-frequency canonical problems such as satellite dish simulations, where modelling precipitation at the particulate level enhances...
In recent years, investigations into accelerating Transmission Line Matrix (TLM) solver programs have concentrated on the use of large-scale parallel computing systems. The focus for such systems rests on leveraging multi-core software architecture principles to achieve improved performances. Mirroring desktop CPU advances of the early 2000s, modern small-scale computing platforms are increasingly...
Modern mobile communication devices share a common set of hardware and software features. Within a brand, it is also common for similar hardware architectures to be used, and to be paired with the same operating system. Whilst mathematically trivial in nature, the Transmission Line Matrix (TLM) method is computationally-intensive, and therefore varies in performance dependant on available resources...
At UHF and EHF wavelengths, air-born precipitation has a significant attenuating and depolarising effect on transmitted radio signals. Analysis of these effects in the time domain, using methods such as the Transmission Line Matrix (TLM) method requires an accurate reproduction of the raindrop geometry in order to obtain the most relevant results. This paper discusses the characteristics of different...
Modern mobile devices have now advanced to a point where they can execute computationally-intensive mathematical problems. The Transmission Line Matrix Modelling method (TLM) is a time-domain method allowing the computation of two and three dimensional electromagnetic fields and structures. TLM is able to model complex scenarios whilst utilising a computationally simple method to model structures...
