This paper presents a compact triple-band planar antenna. The prototype is based on a printed dipole which is excited with Split Ring Resonators (SRRs) as resonant elements to get three frequency bands. To validate the ...

A previous work showed that viscosity values measured high frequency by ultrasound agreed with the values at low frequency by the rotational viscometer when conditions are met, such as relatively low frequency viscosity. ...

The design of an Split Ring Resonator (SRR) based sensor is proposed for pisco concentration measurements through the characterization of the permittivity in liquids solutions containing pisco. The design is composed of ...

Thanks to the revolution in electronics and telecommunications, there is a proliferation of devices for medical applications and others operating in the body area. There is a novel way to connect two transceivers with the ...

A method to characterize the behavior of low frequency voltage dividers, based on the step response, is presented. Amplitude errors and phase displacements can be evaluated, in an absolute way, without any auxiliary standard ...

Characterizing ultrashort laser pulses is a challenging task. By now several methods are established which can be divided into interferometric methods like SPIDER (spectral phase interferometry for direct electric field ...

To ensure high accuracy results from GPS relative positioning, the multipath effects have to be mitigated. Although the careful selection of antenna site and the use of especial antennas and receivers can minimize multipath, ...
