A global simulation code is developed to study the ICRF heating combining two global simulation codes: a full wave field solver, TASK/WM, and a drift kinetic equation solver, GNET. The both codes can treat a 3-D magnetic configuration based on the MHD equilibrium by VMEC code. The developed code is applied to the ICRF minority heating in a simple circular tokamak. The ICRF wave propagation is s...

In addition to the recently proposed full-wave rectifier by Prommee et al. [25] using voltage-mode (VM) two-cell winner-takes-all (WTA) circuit, we present currentmode (CM) precision full-wave rectifier using CM two-cell WTA circuit. The popular Lazzaro’s CM WTA circuit has been employed for the purpose and there is no requirement of inverting the input signal as in [25]. Also, dual complimenta...

The Functional Transformation Method is an established method for digital sound synthesis via physical modeling. It starts from a physical description of the sounding object in form of a partial differential equation and solves it by suitable integral transformation in the frequency domain. After discretization, the resulting algorithms are fast enough to be implemented in full audio sample-rat...

The phase space evolution in a non-relativistic and homogeneous laser plasma in the presence of the stimulated Raman scattering is investigated. The mechanism of the electron acceleration in the potential wells of the plasma wave accompanying the Raman backscattering is analyzed by Vlasov-Maxwell simulations. In addition to the interaction with the primary wave a cascading is observed consistin...

Repeated simulation of large scale wave propagation problems are prevalent in many fields. In oil exploration imaging problems the use of full wave simulations is becoming routinary and it is only hampered by the extreme computational resources required. In this contribution we study the feasibility of employing model order reduction techniques for the wave equation, in an attempt to decrease t...

The fact that the numerical complexity of wavefield simulation is proportional to the size of the discretized model and acquisition geometry, and not to the complexity of the simulated wavefield, is the main impediment within seismic imaging. By turning simulation into a compressive sensing problem—where simulated data is recovered from a relatively small number of independent simultaneous sour...

In this paper, we present a Full-chip CMP simulation system. We discuss three problems in practical use of CMP simulation system: how to handle huge chip data, ECP model accuracy, and how to predict the errors effectively. We propose solutions to the problems as follows: First, we develop a data extraction tool from GDSII. Dummy fill insertion function of this tool can reduce the data size of G...
