Exploring the limits of Fractal Electrodynamics for the future telecomunication technologies

Objective

The aim of this project is basic research on fractal electrodynamics in order to explore the performance limits of highly innovative fractal shaped miniature devices for the future wireless telecommunication systems. This project will: i) explore if fractal devices can reach the fundamental size limit, not reached yet by Euclidean shaped devices, that establishes the smallest size for a given operating bandwidth; ii) assess the viability of such devices in the framework of present technology constraints. The result should be the basis of a new generation of miniature microwave devices such as antennas, filters and resonators. The development of miniature wireless communication sub-systems would remove one of the bottlenecks that prevent the integration of multimedia, communication and remote sensing services in small user terminals, resulting in a significant breakthrough for the Information Society Technologies.

OBJECTIVES
1- Increase the know-how in Fractal Electrodynamics in order to acquire design guidelines for fractal-shaped antennas and microwave devices;
2- Explore if fractal-shaped microwave devices can reach the fundamental miniaturization limit, which has never been reached by Euclidean-shaped devices;
3- Develop a software tool for computer simulation of fractal-shaped microwave devices performance, including time domain visualization of the interaction between geometry and electromagnetic fields, in order to allow a physical interpretation of radiation and resonance of the proposed structures. This tool would allow also the later design and optimisation of such devices;
4- Explore the impact of the technological limitations on the performance of fractal-shaped microwave devices.

DESCRIPTION OF WORK
The aim of this project is basic research on fractal electrodynamics in order to explore the performance limits (fundamental and technological) of highly innovative fractal shaped miniature devices for future wireless telecommunication systems. In fractal devices, the electromagnetic fields acquire fractal properties. The fractal dimension of fields results in a considerable device size reduction. Technological limitations arise since fractals are structures that have details of infinitely small size, which are impossible to implement in practice. The performance of devices having the smallest size compatible with present technology constraints will be studied. There is also a fundamental limit, not reached yet by Euclidean shaped devices, that establishes the smallest size for a given operating bandwidth. The size limitation depends on how efficiently the device occupies the volume inside the enclosing sphere, and thus fractal shapes are expected to perform much better than Euclidean ones. This project will explore if fractal devices can reach the fundamental limit. The result should be the basis for a new generation of miniature microwave devices such as antennas, filters and resonators. The development of miniature wireless communication sub-systems would remove one of the bottlenecks that prevent the integration of multiple information services combining multimedia, communication and remote sensing functionalities in small user terminals like a handy phone, a wristwatch or a credit card, resulting in a significant breakthrough for the IST. The research proposed in this project involves many difficulties to overcome and new fields to develop, which make the success of the project very risky. Due to the multidisciplinary nature of Fractal Electrodynamics, the consortium will include partners with expertise on different fields such as such as electromagnetic theory, fractal mathematics, design of microwave antennas and devices and numerical modelling.
