Here we report a prism made of stacked quasi-selfcomplementary extraordinary transmission surfaces which allows simultaneously left- and right-handed propagation within the V-band for vertical and horizontal polarizations, ...
Development of a low mobility IEEE 802.15.4 compliant VANET system for urban environments
(MDPI, 2013)
Artículo / Artikulua,
The use of Vehicular Ad-Hoc Networks (VANETs) is growing nowadays and it includes both roadside-to-vehicle communication (RVC) and inter-vehicle communication (IVC). The purpose of VANETs is to exchange useful information ...
Frequency selective properties of coaxial transmission lines loaded with combined artificial inclusions
(Hindawi, 2014)
info:eu-repo/semantics/article,
The properties of a modified coaxial transmission line by periodic inclusions will be discussed. The introduction of split ring
resonators, conductor stubs, air gaps, and combination of these gives rise to new frequency ...
