Nonlinear effects are used to specially broaden the spectrum by the interaction with a material at high intensities. Here we study nonlinear effects in a light induced first-order phase transition of a thin layer of VO2. The behaviour that we’ve fo

This paper presents a comparative study between the oblique sounding results, theInternational Telecommunication Union Rec533 HF prediction model, and the vertical sounding results of atransequatorial long haul link. The long haul link is a 12,760 km

This paper presents two digital transmission techniques for long haul ionospheric links. Since2003 we have studied the HF link between the Antarctic Spanish Base, Juan Carlos I, and Spain; and wehave described the link in terms of availability, ignal

A control scheme suited for setting the false alarm rate to a fixed value in Frequency-Hopping Spread-Spectrum Communications is proposed. The scheme performance is determined in the presence of a partial band interference. For this purpose, both ana
