Channel Modelling based on Game Engines Light Physics for mmW in Indoor Scenarios

Inca-Sánchez, Saúl Adrián; Prado-Alvarez, Danaisy; Martín-Sacristán, David; Monserrat del Río, Jose Francisco (IEEE, 2020-03-20)

[EN] The importance of Millimeter Waves (mmW) band for the Fifth Generation (5G) of mobile and wireless communications has motivated a lot of work in mmW channel modelling. In this paper, we assess the use of the light ...
Channel sounding and indoor radio channel characteristics in the W-band

Martínez Inglés, M.T.; Gaillot, D.; Pascual-García, Juan; Molina-García-Pardo, José María; Rodríguez Rodríguez, José Víctor; Rubio Arjona, Lorenzo; Juan Llácer, Leandro (Hindawi Publishing Corporation, 2016-01-28)

This work presents directional radio channel measurements in the W-band using a commercial versatile channel sounder based on a vector network analyzer (VNA), capable of measuring scattering parameters from 75 to 500 GHz ...
Dual-band double-negative-index fishnet metamaterial at millimeter-waves

Navarro-Cia, M.; García Meca, Carlos; Beruete, M.; Martínez Abietar, Alejandro José; Sorolla, M. (Optical Society of America, 2011)

[EN] An effective negative refractive index (NRI) is demonstrated and experimentally verified for the first two propagation bands of a fishnet-like metamaterial at millimeter-wave frequencies. The dual-band NRI behavior ...
EAM-SOA millimeter-wave frequency up-converter for radio-over-fiber applications

Palací López, Jesús; Villanueva Ibáñez, Guillermo Eduardo; Herrera, J. (Elsevier, 2011-01-01)

[EN] We present an optical scheme for photonic frequency up-conversion at the millimeter-wave bands based on Semiconductor Optical Amplifier. The proposed scheme modulates the bias current with the Intermediate Frequency ...
Experimental investigation of non-thermal millimeter wave effects on conductivity in aqueous electrolyte solutions

Molero Alabau, Rubén (Universitat Politècnica de València, 2019-11-22)

[ES] Se ha demostrado en diversos estudios los efectos no térmicos de las ondas milimétricas (MMW) en sistemas biológicos. Algunos autores han demostrado que las MMW pueden mejorar la difusión de los iones en soluciones ...
Gap Waveguides using a suspended stripon a bed of nails

Valero-Nogueira, Alejandro; Baquero Escudero, Mariano; Herranz Herruzo, José Ignacio; Doménech Navarro, Javier; Alfonso Alós, Esperanza; Vila Jiménez, Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2011)

This letter discusses the feasibility of a new type of waveguide consisting of a strip suspended on a bed of nails. The bed of nails enforces a stopband, while the strip opens a propagating path that can be used to design ...
Impact of Thermal-Induced Turbulent Distribution Along FSO Link on Transmission of Photonically Generated mmW Signals in the Frequency Range 26¿40 GHz

Vallejo-Castro, Luis; Komanec, Matej; Ortega Tamarit, Beatriz; Bohata, Jan; Nguyen, Dong-Nhat; Zvanovec, Stanislav; Almenar Terre, Vicenç (Institute of Electrical and Electronics Engineers, 2020-02)

[EN] Microwave photonics is a promising solution to transmit millimeter wave (mmW) signals for the 5th generation (5G) mobile communications as part of a centralized radio access network (C-RAN). In this paper, we ...
Reconfigurable slot-array antenna with RF-MEMS

Sánchez Escuderos, Daniel; Ferrando Bataller, Miguel; Baquero Escudero, Mariano; Herranz Herruzo, José Ignacio (Institute of Electrical and Electronics Engineers (IEEE), 2011)

Cylindrical near-field measurement systems are being widely demanded, especially for imaging applications at millimeter-wave frequencies. One of their most important drawbacks is the long time required to perform a full ...
Serious Game Engineering and Lighting Models for the Realistic Emulation of 5G Systems

Inca Sánchez, Saúl Adrián (Universitat Politècnica de València, 2019-12-11)

[ES] La quinta generación de comunicaciones móviles, 5G, promete ser una revolución tecnológica que vaya más allá de multiplicar la velocidad de transmisión de datos de sus predecesoras. Pretende soportar una gran cantidad ...
