We present the first fundamental simulation method for the determination of crater morphology due to femtosecond-pulse laser damage. To this end we have adapted the particle-in-cell (PIC) method commonly used in plasma physics for use in the study of laser damage and developed the first implementation of a pair potential for PIC codes. We find that the PIC method is a complementary approach to ...

One of the promising techniques to allow highspeed data transmission with a limited bandwidth is multiinput multi-output (MIMO) multiplexing. As a signal separation scheme, an iterative frequency-domain interference cancellation (FD-IC) using two-dimensional minimum mean square error (2D-MMSE) frequencydomain equalization (FDE) was recently proposed. There are two types of FD-IC: parallel FD-IC...

Particle-in-cell (PIC) plasma simulation codes require two data arrays—particle array and field array—for storing the lists of particles and electromagnetic fields, respectively. In every iteration the two are updated based on the values of each other. The interaction between these two arrays is dynamic due to the movement of particles. Efficient parallelization of PIC requires the two data arr...

A study of the application of blind adaptive Minimum Mean Square Error (MMSE) and Parallel Interference Cancellation (PIC) multiuser detection techniques to Wideband Code Division Multiple Access (WCDMA), the physical layer of Universal Mobile Telecommunication System (UMTS), has been performed as part of the Freeband Adaptive Wireless Networking project. This study was started with an analysis...

The Weibel instability is investigated with PIC simulations of an initially unmagnetized and spatially uniform electron plasma. This instability, which is driven by the thermally anisotropic electron distribution, generates electromagnetic waves with wave vectors perpendicular to the direction of the higher temperature. Two simulations are performed: A 2D simulation, with a simulation plane tha...

In this paper, we present the performance of a parallel interference cancellation (PIC) scheme in Code division multiple access with cyclic prefix (CP-CDMA) systems and proposed a new model for cyclic prefix code division multiple access with less complexity and good resistance to near-far effect. This method is mostly used for broadband wireless communication in the uplink. Parallel interferen...

Gyrokinetic particle-in-cell (PIC) simulation is an important tool for studying low-frequency (! !ci) plasma instabilities and the associated transport of particles and heat in tokamaks. In spite of the e ciency gained by not following ion cyclotron motion, more e ciency is needed in performing simulations on a transport timescale: using 1 million particles in a system of 64 128 32 grid cells, ...
