Title: Multi-level Fast Multipole Algorithm for 3-D Homogeneous Dielectric Objects Using MPI-CUDA on GPU Cluster
Abstract: The implementation of Multi-level Fast Multipole Algorithm (MLFMA) on a 13-node Graphical Processing Unit (GPU) cluster using Message Passing Interface (MPI) and CUDA programming is presented. The performance achievements are investigated in terms of accuracy, speed up, and scalability. The experimental results demonstrate that our MLFMA implementation on GPUs is much faster than (up to 66x) that of the CPU implementation without trading off the accuracy.

Title: A Substrate Integrated Waveguide Based Antipodal Linear Tapered Slot Antenna for 60 GHz Wireless Communications
Abstract: Antipodal linear tapered slot antenna (ALTSA) for 60 GHz communications is presented in this paper. To obtain a high gain, dielectric loading in addition to the corrugation structure is applied to the ALTSA. The use of substrate integrated waveguide (SIW) technology allows a highly efficient, compact and low cost planar design. The antenna is designed and simulated in an electromagnetic field simulation tool. To validate the proposed design, a prototype has been fabricated and measured. The simulated results agree well with the measured values, which validates the proposed design. The radiation efficiency is observed to be 92%. The antenna has a gain of 18.7 0.5 dBi. The return loss is better than 10 dB over the 60 GHz band (57 GHz 64 GHz).

Title: Installed Antenna Performance in Airborne Radomes of Different Profiles
Abstract: In this paper, broadband interactions between an antenna and a radome are modelled using a full wave numerical solver. By accurately describing both the antenna and the radome geometry with a single numerical method, a comprehensive prediction of the performance of the coupled antenna and radome installation is provided. The paper compares how different airborne dielectric radome profiles affect the antenna performance, predicting effects not seen in uncoupled simulations.

Title: A Compact Fractal Monopole Antenna with Defected Ground Structure for Wideband Communication
Abstract: A compact fractal monopole antenna with defected ground structure has been investigated in this paper. A wide bandwidth of 3.13 GHz (3.42 GHz to 6.55 GHz) has been obtained, which covers the IEEE 802.11 WLAN bands (5.2 GHz and 5.8 GHz) and WiMAX bands (3.5 GHz and 5.5 GHz). The dimension of the structure is 14.50 X 27.25 mm2 covering an area of only 395.125 mm2. The realized antenna gain is ? 2 dBi at the frequencies of interest. The compactness of the proposed structure and the simplicity of design makes it easy to be fabricated and incorporated in devices suited for wireless communication purpose.
