| Title: | Efficient Electromagnetic Simulation Including Thin Structures by Using Multi-GPU HIE-FDTD Method |
| Abstract: | This paper describes an efficient simulation method to solve the large scale electromagnetic problems with thin unit cells in the finite-difference time-domain (FDTD) simulation. The proposed method is based on the hybrid implicit-explicit and multi-GPU techniques, which can choose a larger time step size than that in the conventional one, and using the multiple graphic processing units (GPUs). In the proposed method, the computational time is significantly reduced |

| Title: | On The Beam Forming Characteristics of Linear Array Using Nature Inspired Computing Techniques |
| Abstract: | Beamforming is a serious problem in wireless communication. Many deterministic and numerical techniques are proposed to achieve beamforming. However, the application of evolutionary computing techniques produced better results over many existing conventional methods. In this paper, one such attempt of applying a novel nature-inspired technique known as Firefly algorithm (FFA) to demonstrate beamforming in linear arrays and compared with particle swarm optimization (PSO). The desired objectives of the synthesis process are defined as sidelobe level (SLL) suppression and null positioning. The optimal set of amplitude distribution for the elements in the linear array is obtained using the technique in order to achieve the desired objectives. The results are evaluated in terms of radiation pattern plots. |

| Title: | Bandwidth Enhancement of Dipole Antennas using Parasitic Elements |
| Abstract: | Dipole antennas have a limited bandwidth which restricts their use to narrow bandwidth applications. To improve the functionality of a dipole antenna, additional wire elements can be added to the dipole antenna to increase the impedance matching and bandwidth. A design for a modified dipole antenna is proposed and analyzed using multiple computational electromagnetic software to determine how the additional wire elements affect the input impedance bandwidth and radiated fields. The antenna was then fabricated and tested and compared to simulation results. The modified dipole antenna shows a bandwidth improvement of more than four times, approaching 31%, while maintaining radiation patterns similar to a traditional dipole antenna with slightly higher gain. |

| Title: | CUDA-MPI Implementation of Fast Multipole Method on GPU Clusters for Dielectric Objects |
| Abstract: | This paper investigates the Fast Multipole Method (FMM) for large-scale electromagnetics scattering problems for dielectric objects. The algorithm is implemented on a Graphical Processing Unit (GPU) cluster using CUDA programming and Message Passing Interface (MPI). Its performance is investigated in terms of accuracy, speedup, and scalability. The details of the implementation and the performance achievements are shown and analyzed, demonstrating a scalable parallelization while maintaining a good degree of accuracy. |
