Multi-iluminación en Microondas con Estado Sólido 1Universidad Politécnica de Valencia, España; 2Microbiotech S.L. The industrial applications of microwaves are restricted in the ISM band (Industrial, Scientific & Medical). For few years ago, the power source of this kind of applications was focused on basically in magnetron (high performance oscillator tube). Nowadays, there are sources based on solid state which have high performance, and are able to reach more than 1000W power with a unique transistor. This means that, taking in account all the advantages of solid state (such as spectral purity, control, electrical safety, reliability…), is possible to use multiples illuminations on the load, controlling power, frequency and phase of each antenna, all inside a microwave cavity.

Aplicación de Trazado de Rayos en Antenas Leaky-Wave Combinadas con Lentes Dieléctricas 1Universidad Politécnica de Cartagena, España; 2Universidad de Sevilla, España; 3Ericsson Research, Suecia; 4KTH Royal Institute of Technology, Suecia The application of ray-tracing for the efficient analysis of curved leaky-wave antennas combined with shaped dielectric lenses is presented in this work. Thanks to the ray-tracing technique, based on geometrical optics, the phase and amplitude of the fields at the lens aperture is obtained with low computational load. This computation also takes into account the reflections due to the change of media between the lens and the air. With this, the far-field radiation pattern is accurately and efficiently calculated using Kirchhoff's scalar diffraction theory. The results are validated against full-wave simulations, achieving a significant time reduction above 99%.

Implementación de un simulador 2D de elementos finitos en Julia Universidad Carlos III de Madrid, España Este articulo se centra en el desarrollo de un simulador 2D basado en el método de elementos finitos (FEM) implementado en el lenguaje Julia para resolver el campo electromagnético en el interior de una guía de ondas. Este desarrollo es una prueba de concepto para probar el entorno de trabajo y las prestaciones computacionales de Julia, que es una herramienta con cierta expansión en el campo de la computación científica pero no el en el del electromagnetismo computacional. En este trabajo se describe la formulación del problema, la metodología de implementación, y se verifica el correcto funcionamiento del código con la resolución de los modos de funcionamiento de una guía de ondas rectangular, que tiene solución analítica.

Characterization of Microwave Filters Using Machine Learning Techniques Universidad Politécnica de Madrid, España The characterization of the frequency response of microwave filters has traditionally been carried out through rigorous analysis and simulations based on theoretical models, which can be complex and time-consuming. By training neural networks on input-output pairs obtained from filter measurements or simulations across a range of frequencies, the model learns to accurately predict the response of the filter for unseen inputs. This methodology offers several advantages over traditional methods, including faster analysis, reduced computational complexity, and the ability to handle complex filter responses. In this work, we use Machine Learning techniques for the characterization of microwave filters. In particular, we propose a neural network which is able to estimate S and Z-parameters for a given frequency band, taking as input the dielectric material parameter configuration of the microwave filter.
