Abstract:

Multiple scattering effects from bubble clouds are investigated in this study. A high performance, general purpose numerical tool for multiple scattering calculations is developed. This numerical tool is applied in three computational scenarios in this study. The total scattering cross section of a bubble cloud is investigated. Numerical results indicate that the resonant frequency of the bubble cloud is much lower than that of a single bubble. The variation of resonant frequency of multiple scattering is also studied. It is found that the resonant frequency decreases as the number of bubbles

Abstract:

The interaction between coherent waves and material systems with complex optical properties is a complicated, deterministic process. Light that scatters from such media gives rise to random fields with intricate properties. It is common perception that the randomness of these complex fields is undesired and therefore is to be removed, usually through a process of ensemble averaging. However, random fields emerging from light matter interaction contain information about the properties of the medium and a thorough analysis of the scattered light allows solving specific inverse problems.

Abstract:

Understanding the phenomenon of wave scattering by random media is a ubiquitous problem that has instigated extensive research in the field. This thesis focuses on wave scattering by quasiperiodic media as an alternative approach to provide insight into the effects of structural aperiodicity on the propagation of the waves. Quasiperiodic structures are aperiodic yet ordered so have attributes that make them beneficial to explore. Quasiperiodic lattices are also used to model the atomic structures of quasicrystals; materials that have been found to have a multitude of applications due to their

Abstract:

The Muon Ionisation Cooling Experiment (MICE) was designed to provide the first demonstration of muon ionisation cooling by passing a muon beam through a cooling channel consisting of low-Z absorber material as well as radio-frequency (RF) cavities, with the net effect of a reduction in transverse momentum spread at constant total momentum. The performance that can be achieved in such a cooling channel depends on both energy loss and multiple coulomb scattering in the absorber, the latter of which is currently not understood to very high precision for muons.

Abstract:

The International Muon Ionisation Cooling Experiment (MICE) aims to give the first demonstration of ionisation cooling. MICE will use a low Z absorber to first reduce the momentum of a muon beam; then use a series of radio-frequency (RF) cavities to restore its longitudinal momentum. This action will reduce the overall phase-space volume of the muon beam. The goal of MICE is to reduce the emittance of a muon beam by 5\% and to measure the change in emittance to a precision of 1%. In 2011 MICE took data in its Step I configuration with the goal of understanding the muon beam that will serve the

Low observable technology is used in order to prevent detection, or to delay detection. Radar cross section is an important parameter in aircraft survivability since it measures how detectable an object is with radar. To find the radar cross section Maxwell's equations are solved numerically in the time-domain using a finite difference scheme. This numerical method called Finite Difference Time Domain is very suitable for structures including complex materials. However, this numerical method needs to be verified for large scale simulations, due to numerical dispersion errors. Therefore it is d

Abstract:

Light scattering-based techniques are being developed for non-invasive diagnostics of inhomogeneous media in various fields, such as medicine, biology, and material characterization. However, as most media of interest are highly scattering and have a complex structure, it is difficult to obtain a full analytical solution of the scattering problem without introducing approximations and assumptions about the properties of the system under consideration. Moreover, most of the previous studies deal with idealized scattering situations, rarely encountered in practice. This dissertation provides new

Abstract:

For problems of time harmonic wave scattering, standard numerical methods (using piecewise polynomial approximation spaces) require the computational cost to grow with the frequency of the problem, in order to maintain a fixed accuracy. This can make many problems of practical interest difficult or impossible to solve at high frequencies. The Hybrid Numerical Asymptotic Boundary Element Method (HNA BEM) overcomes this by enriching the approximation space with oscillatory basis functions, in such a way that accuracy may be maintained with a computational cost that grows only modestly with frequ

Lateral light scattering in fibrous media is investigated by computing the modulation transfer function (MTF) of 22 paper samples using a Monte Carlo model. The simulation tool uses phase functions from infinitely long homogenous cylinders and the directional inhomogeneity of paper is achieved by aligning the cylinders in the plane. The inverse frequency at half maximum of the MTF is compared to both measurements and previous simulations with isotropic and strongly forward single scattering phase functions. It is found that the conical scattering by cylinders enhances the lateral scattering an

This type of response is called a multiple. In general, multiples in seismic data fall into two categories: (1) events that bounce at least once at the free surface in addition to any other bounce in the sub- surface
