Diffraction of electromagnetic wave beams Abstract: The diffraction of electromagnetic wave beams is studied theoretically and experimentally. The theoretical analysis consists of applying the angular spectrum method and the FDTD numerical simulation method. The frequency response and the angular distribution of the diffracted field are studied. Flat near-field measurements in anechoic chamber are used. Field of application:
Minimisation of radar response.
Non-destructive analysis using electromagnetic fields.
Propagation-scattering properties and radio-communications. Measurements of passive devices and microwave antennas Abstract: Microwave antennas and devices must be designed for each specific application: frequency response and polarisation, gain and radiation pattern in case of antennas. For instance, size restrictions, features regardless of the environment, user-friendly appearance and low cost. A very important part of the prototype design process is the measurements. Measurements are performed in an anechoic chamber with a 45MHz-110GHz vector network analyser. Measurements can be carried out in far-field, or in near-field for large antennas or reflectors, making...Diffraction of electromagnetic wave beams Abstract: The diffraction of electromagnetic wave beams is studied theoretically and experimentally.

Measurements can be carried out in far-field, or in near-field for large antennas or reflectors, making the near to far-field transformation. Field of application:
Antenna development.
Radio-communications.
Calibration of radio-frequency equipment. Computational electromagnetics Abstract: Maxwell equations are solved numerically to take into account boundary conditions and complex materials. The Finite-difference time-domain (FDTD) technique, spectral methods and the Transmission-line matrix (TLM) technique are used. The use of several techniques in the analysis of an electromagnetic structure allows the veracity of the results to be guaranteed, especially for the development of prototypes. Processing, optimisation and classification techniques such as neural networks are used. Field of application:
Design of Radio Frequency devices: Antennas and other passive radio frequency elements.
Simulation of problems of propagation, penetration, diffusion and dispersion of electromagnetic waves.
Study of the electromagnetic behaviour of complex structures: Electromagnetism of planetary atmospheres. Environmental electromagnetic field measurements Abstract: Environmental electromagnetic field measurements are carried out. Radiofrequency measurements associated with wireless communication systems. Measurements of electromagnetic fields of natural origin. Terrestrial geomagnetic field measurements. Low-frequency field measurements associated with network wiring, high-voltage wiring and transformers. Electromagnetic field shielding. Carrying out of electromagnetic field maps of natural and artificial origin. Field of application:
Electromagnetic pollution assessment.
Environmental health.
Minimisation of electromagnetic pollution. Biomass processing and logistics Abstract: In the surroundings of the Albufera, about 280,000 tonnes of biomass are generated. Its use not only involves an environmental challenge, but also an economic one. The study of its use, logistics, and the use of electromagnetic treatments would not only reduce emissions to the atmosphere, but also generate economic activity at a local level and reduce imports of raw materials.Campo de aplicación:
Agro-economics.
Energy.
Recycling.
