A ray launching-neural network approach for radio wave propagation analysis in complex indoor environments
(IEEE, 2014)
Artículo / Artikulua,
A novel deterministic approach to model the radio
wave propagation channels in complex indoor environments
reducing computational complexity is proposed. This technique
combines a neural network and a 3D ray launching ...
Analysis of radio wave propagation for ISM 2.4GHz wireless sensor networks in inhomogeneous vegetation environments
(2014)
Contribución a congreso / Biltzarrerako ekarpena,
The use of wireless networks has been extended in an exponential growing due to the improvement in terms of battery life and low consumption of the devices. However, it is highly important to conduct previous radio propagation ...
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 ...
All-metallic ε-near-zero (ENZ) lens based on ultra-narrow hollow rectangular waveguides: experimental results
(IEEE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
Here we perform numerical and experimental investigation of plano-concave all-metallic ε-near-zero (ENZ) lens with operational frequency f = 144 GHz. The ENZ lens is achieved by stacking an array of narrow hollow rectangular ...
