H. Wang, A. Trakic, F. Liu, M. E. Bialkowski, S. Crozier School of Information Technology and Electrical Engineering, University of Queensland, Brisbane, Queensland, Australia Synopsis: In recent years, Magnetic Resonance technology has progressed towards improved image resolution and acquisition speed. As a result, obtaining analogous high-resolution images via an electromagnetic (EM) field an...

PIC method of plasma simulation is widely used in plasma physics research because of its ability to solve wide range of problems in kinetic approach. Regarding to description of PIC method we refer to [Birdsall et al., 1995]. This work is focused on PIC simulations of dc discharge in cylindrical magnetron device. Magnetrons are used in industry e.g. for thin film layer coating and etching. Many...

The aim of our work is to study the effect of geometry variation on nucleation times and to address its role in the context of eukaryotic chemotaxis (i.e. the process which allows cells to identify and follow a gradient of chemical attractant). As a first step in this direction we study the nucleation dynamics of the 2d Ising model defined on a cylindrical lattice whose radius changes as a func...

Laser-scan acquisitions were obtained from real human heads and processed for the construction of a database of anthromomorphical phantoms for dosimetry studies of hand-held mobile phones. Raw data was converted to cylindrical range images and several image processing techniques were then applied to filter and smooth the profiles for 3D-model construction. A triangulated surface was then obtain...

This paper estimates separately the components of scattering waves generated in cylinder-body model for body area networks. For the evaluation, scattering field formulations in relation to uniform cylinderand slab-body models are provided, and the reliability of the analyses is testified by the comparison with results computed by the finite-difference time-domain (FDTD) method. Creeping waves, ...

This paper presents a new design of conformal microstrip antenna operating in dual-band for several applications including Wireless Local Area Networks (WLAN), Wi-Fi networks, and Body (WBAN). The proposed was achieved using the stacked patch technique on antenna. One patches is square-shaped other triangular-shaped constructed cylindrical surface with 50 mm radius substrate permittivity 2.98. ...

ABSTRACT. A numerical method was used to analyse the interaction of L-band microwaves with pine (Pinus merkusii) trunk. This method approximated tree trunk as an infinite length of two layers of cylindrical dielectric media. These layers are xylem and heartwood. Horizontal polarisation (transverse magnetic mode) of the scattered wave was derived in order to determine the relationship between tr...

Use of surface plasmons in photovoltaics is a recent and fast emerging field of interest of research that exploit the unique optical properties of metallic nano-structures. Using surface plasmons for guiding and localizing light at nanoscales can be used to improve optical absorption in thin-film solar cells. The present work focuses on the study of absorption enhancement using a periodic array...
