Estudio de señales auditivas en lobos (Canis lupus signatus) en cautividad
(2020)[Resumen]: Los aullidos de los lobos son elementos comunicativos complejos y fundamentales para la vida en grupo, en sus estrategias de caza o para la defensa del territorio. Sin embargo, son menos conocidas las ... -
New Toroidal Beam Antennas for WLAN Communications
(Institute of Electrical and Electronics Engineers, 2007-02)[Abstract] The design of a number of new antennas that radiate linearly polarized toroidal beams is described. The developed procedures are based on the use of a method of moments commercial software tool. Several numerical ... -
Optimizing Uniformly Excited Linear Arrays through Time Modulation
(Institute of Electrical and Electronics Engineers, 2004-12)[Abstract] The letter shows that, by the proper use of time modulation in equispaced linear arrays with uniform excitation distribution, it is possible to maintain the sidelobe zone of the radiated power below a certain - ... -
Variation in The Bandwidths of Pattern-Quality Parameters and Maximum Embedded Impedance among the Solutions to Shaped-Beam Synthesis Problems for Collinear Dipole Arrays
(Institute of Electrical and Electronics Engineers, 2003)[Abstract] We investigated variation in the bandwidths of ripple, sidelobe level, -3 dB beamwidth, and maximum element embedded (active) impedance (|Z/sup e/|/sub max/) among multiple collinear dipole arrays radiating a ...
