In this paper a new analytical method to design stop-band filters combining the Bragg and resonant effects is presented. A rigorous consideration of the EBG structures filtering effect at the microwave frequency range will be performed. We will show that in that frequency range, the periodic structure filtering effect (or Bragg effect) and the self-resonance of the different cells involved are tuned approximately at the same frequencies, mixing their influences in the final filter response. Both effects are defined by different geometrical laws, and filters with very interesting properties such as high rejections, sharpness and reduced insertion losses, can be obtained when tuning the EBG effect and the resonant effect at the same frequency.

This thesis discusses the implementation of Sigma-Point Kalman Filters (SPKF) for state estimation of nonlinear wind turbine systems. First, a theoretical review of nonlinear Kalman filtering is given. Then the different ...
Multi-tap complex-coefficient incoherent microwave photonic filters based on optical single-sideband modulation and narrow band optical filtering Sagüés García, Mikel ; García Olcina, Raimundo; Loayssa Lara, Alayn ; Sales, Salvador; Capmany, José (Optical Society of America, 2008) Artículo / ArtikuluaWe propose a novel scheme to implement tunable multi-tap complex coefficient filters based on optical single sideband modulation and narrow band optical filtering. A four tap filter is experimentally demonstrated to highlight ...
Suppression of narrowband interference generated by the power supply of the railway systems in public defibrillators devices A specific problem using the public access defibrillators arises at the railway stations. Some countries as Germany, Austria, Switzerland, Norway, Sweden and Slovenia are using AC railroad net power-supply system with ...
