In this paper, we propose a systematic procedure for the accurate design of classical dual-mode filters in circular waveguide technology. The design procedure is based on the previous synthesis of an intermediate distributed ...
The first step to detect when a vineyard has any type of deficiency, pest or disease is to observe its stems, its grapes and/or its leaves. To place a sensor in each leaf of every vineyard is obviously not feasible in terms ...
Belloch Rodríguez, José Antonio; Alventosa, Fran J.; Alonso-Jordá, Pedro; Quintana Ortí, Enrique Salvador; Vidal Maciá, Antonio Manuel(Springer Verlag (Germany), 2017-01)
Tablets and smart phones are nowadays equipped with low-power processor
architectures such as the ARMv7 and the ARMv8 series. These processors integrate
powerful SIMD units to exploit the intrinsic data-parallelism of ...
An Agressive Space Mapping (ASM) strategy for efficiently and accurately designing passive filters in substrate integrated waveguide (SIW) technology is presented and successfully validated for the double post topology. ...
