Optimization of a pin surface as a solution to suppress cavity modes in a packaged W-band microstrip receiver
(IEEE, 2014)
Artículo / Artikulua,
A pin surface structure has been used in the upper
metal plate of a packaged W-band RF front-end receiver in order
to suppress the propagation of unwanted modes. A full parametric
analysis of the periodic structure within ...
Broadband radar cross-section reduction using AMC technology
(IEEE, 2013)
Artículo / Artikulua,
This paper presents the design, fabrication and characterization of a planar broadband chessboard structure to reduce the radar cross-section (RCS) of an object. The chessboard like configuration is formed by combining two ...
Circuit and multipolar approaches to investigate the balance of powers in 2D scattering problems
(EMW Publishing, 2013)
Artículo / Artikulua,
Circuit and multipolar approaches are presented to investigate the correlation between absorption and scattering processes in 2D problems. This investigation was inspired by earlier works of Prof.R.E. Collin, which pointed ...
Surface waves of finite size electromagnetic band gap woodpile structures
(EMW Publishing, 2011)
Artículo / Artikulua,
This paper studies the surface modes at the interface of finite size Electromagnetic Band Gap (EBG) woodpile structures. The impact of different types of woodpile terminations on the properties of these surface modes is ...
Upper bounds on scattering processes and metamaterial-inspired structures that reach them
(IEEE, 2014)
Artículo / Artikulua,
The physical limitations on time-harmonic scattering processes are investigated on the basis of the optical theorem. Previously derived least upper bounds on the total scattering and absorption cross-sections are obtained ...
Superbackscattering antenna arrays
(IEEE, 2015)
Artículo / Artikulua,
This article discusses the theory, design and practical implementation of superbackscattering antenna arrays. In analogy with Uzkov’s maximal directivity theorem, it is demonstrated that the maximal backscattering ...
Decoupling of multifrequency dipole antenna arrays for microwave imaging applications
(Hindawi Publishing Corporation, 2010)
Artículo / Artikulua,
The mutual coupling between elements of a multifrequency dipole antenna array is experimentally investigated by S-parameter
measurements and planar near-field scanning of the radiated field. A multifrequency array with ...
Dispersion properties of an elliptical patch with cross shaped aperture for synchronized propagation of transverse magnetic and electric surface waves
(MDPI, 2018)
Artículo / Artikulua,
This paper presents a novel pixel geometry for the implementation of metasurfaces requiring synchronized phase propagation of transverse magnetic (TM) and transverse electric (TE) modes. The pixel is composed by an elliptical ...
300 GHz optoelectronic transmitter combining integrated photonics and electronic multipliers for wireless communication
(MDPI, 2019)
info:eu-repo/semantics/article,
THz communications systems at carrier frequencies above 200 GHz are the key to enable next-generation mobile communication networks with 100 Gbit/s wireless data rates. One of the key questions is, which carrier frequency ...
A simplified design inline microstrip-to-waveguide transition
(MDPI, 2018)
Artículo / Artikulua,
A simplified design of an inline transition between microstrip and rectangular waveguide is presented in this paper. The transition makes use of a dielectric filled rectangular waveguide (DFRW) as an intermediate step, ...
