A doctoral thesis from the Polytechnic University of Cartagena (UPCT) has developed three new types of cells for microwave devices that reduce the size of the telecommunications systems.
The investigation of Juan de Dios Ruiz is based on the use of electromagnetic metamaterials crystals and resonators for designing compact filters in planar technology.
"The planar technology is a mature method of manufacturing and low-cost devices based on metamaterial structures have unique electromagnetic properties that reduce the size and overcome the limitations of conventional devices," explains the director of the thesis, Juan Hinojosa.
Among the different existing metamaterials, researchers at the Department of Electronics, Computer Technology and Projects UPCT used electromagnetic crystals based on fractals and Veselago media, a so-called left-handed materials, allowing the spread of regressive waves, etc. unusual phenomena.
During the investigation there have been other improvements such as direct connection to the transmission line and easier to design devices reduced in size.
"Cells and proposed may be of great interest for future communication systems devices," said the author of the research, which also highlights, from his position as professor at the School of Art, the "elegance and consistency Fractal Design ".
