Ignition Process of Microplasmas

H. Porteanu, and R. Gesche
Ferdinand-Braun-Institut für Höchstfrequenztechnik, Berlin, Germany

Microplasmas at atmospheric pressure are required in many applications, where treatments in normal ambient, with spatial resolution, are important. The interest on such miniaturized sources has increased due to the availability of a new generation of microwave sources based on high power GaN transistors. The present work deals with a simulation of the plasma formation after the application of ...

Numerical and Experimental Analysis of Natural and Mixed Convection Heat Transfer for Vertically Arranged DIMM

G. Petrone, and G. Cammarata
University of Catania, Catania, Italy

 It is commonly recognized that careful thermal design of electronic equipments represents an unavoidable pre-production step in order to ensure reliability and performance of those components during their functioning. This paper mainly concerns a comparison between experimental and numerical results obtained in studying thermal dissipation in natural and mixed convection conditions for RAM ...

Wavebased Micromotor for Plane Motions (3-DoF)

G. Jehle, D. Kern, and W. Seemann
Karlsruhe Institute of Technology (KIT), Karlsruhe, Germany

This paper proposes the design of a 3-Degree of Freedom(DoF) motor based on surface acoustic waves in elastic solids. The rotor is propelled by wave fields, for linear and rotational motion respectively, in the stator, that can be steered by the driving signal of the piezoelectric actuators, which are placed on an elastic plate. The next considerations concern the feasibility of the proposed ...

Finite Element Analysis of Multilayer Transmission Lines for High-Speed Digital Interconnects

S.M. Musa, and M.N.O. Sadiku
Prairie View A&M University, Prairie View, TX, USA

In this paper, we consider the finite element modeling of multilayer transmission lines for high-speed digital interconnects. Using COMSOL we mainly focused on the modeling of the transmission structures with both cases of symmetric and asymmetric geometries. We specifically designed asymmetric coupled microstrips and four-line symmetric coupled microstrips with a two-layer substrate. We ...

Landmines are an open problem in many countries of the world. They cause injuriesand death and no technique proposed to date guarantees fast and 100% reliable detection alone. To this purpose, at the Humanitarian Demining Laboratory of “La Sapienza” University of Rome, several solutions are being studied. In this paper, numerical simulations of a prototype thermal detection system are reported, ...
