Rotational temperatures in RF plasma of Ar-H2O mixtures at low and moderated pressure

Adriana Annusova, Jaroslav Krištof, Corinne Foissac, Pavel Veis, Philippe Supiot

An Ar-H2O discharge with Ar content from 0 to 95 % at 67 and 266 Pa have been studied by optical emission spectroscopy. The plasma was excited at 27 MHz by a helical cavity with a power set at 30 W. The rotational temperatures of N2(C3Πu) and OH(A2 Σ + ) emitters were determined through spectral...

A 0-level packaged RF-MEMS switched wideband GaAs LNA MMIC

A. Gustafsson, C. Samuelsson, R. Malmqvist, S. Seok, M. Fryziel, N. Rolland, B. Grandchamp, T. Vähä-Heikkilä, R. Baggen

This paper focuses on the design of an RF-MEMS Dicke switched wideband LNA realized in a GaAs MMIC process that also includes a BCB cap type of wafer-level package. The 0- level packaged GaAs MEMS LNA circuit shows 10-17 dB of gain at 16-34 GHz when switched on. The off-state LNA gain is below -6...

Doubly coded Costas signals for grating lobes mitigation

Nadjah Touati, Charles Tatkeu, Thierry Chonavel, Atika Rivenq

In this paper, a novel design scheme for radar signal is proposed. It is based on a modification of Costas codes design by increasing the frequency separation of frequency hops beyond the orthogonality condition. Indeed, Costas codes are well known for their good range-doppler properties. Their...

General solution to the Hertz-Mindlin problem via Preisach formalism

Vladislav Aleshin, Koen van den Abeele

In this paper we analyze the contact problem for two elastic spheres with friction (the Hertz–Mindlin or HM problem) and present an original solution expressed in terms of the Preisach description. The major obstacle for an efficient use of the HM mechanics in the case of general loading histories...

Giant rotary power of a fishnet-like metamaterial

S.X. Wang, F. Garet, Eric Lheurette, M. Astic, J.L. Coutaz, D. Lippens

We show experimentally and numerically that cholesteric-type metal-dielectric structures, made of twisted sub-wavelength hole elliptical–shaped arrays, exhibit strong optical activity and circular dichroism. The experimental demonstration is carried out with terahertz time-domain spectroscopy...

Enhanced gold film-coupled graphene-based plasmonic nanosensor

Rana Nicolas, Thomas Maurer, Gaëtan Lévêque, P. Subramanian, Julien Proust, Jérémie Béal, Silvere Schuermans, Jean-Pierre Vilcot, Z. Herro, M. Kazan, Jerome Plain, Rabah Boukherroub, Abdellatif Akjouj, Bahram Djafari-Rouhani, Pierre-Michel Adam, Sabine Szunerits

In this work, a trilayer graphene is used as a thin non dielectric spacer with a high index of refraction, between Au film and Au NPs. Encouraged by the sharpness of the localized surface plasmon resonance LSPR induced by this system, we performed sensitivity measurements to refractive index change...

Open problems in mathematical modelling and physical experiments: exploring exponential function

Raffaele Pisano, Paolo Bussotti

Generally speaking the exponential function has large applications and it is used by many non physicians and non mathematicians, too. Nevertheless some crucial and practical problems happen for its mathematical understanding. Mostly, this part of mathematical cognitive programmes introduce it from...
