Characterizing the structure of transmission matrix in lower dimensions
… fiber gets scrambled, which is described by the Transmission Matrix (TM) of the fiber. Methods so far have been successful in determining a good approximation of TM only for weakly deformed fibers. We will look into calibration-free, real-time methods to determine the TM of a fiber with …

Using otoacoustic emissions to measure the transmission matrix of the middle-ear
… experimental method for measuring the acoustic transmission matrix of the middle-ear using otoacoustic emissions. The experiment builds on previous work that uses distortion product otoacoustic emissions (DPOAEs) as an intracochlear sound source to drive the middle-ear in reverse. This technique …

Computational imaging in biology
… algorithms are also examined. Reflection matrix based imaging methods allow for diffraction limited imaging through deep tissue which induces large aberrations as well as multiple scattered photon background. Several reflection matrix based imaging techniques are applied as well as …

Optical polarization control in free space and through random media using wavefront shaping
… regard, we introduce the concept of the vector transmission matrix (VTM) by generalizing the conventional transmission matrix. We develop a novel technique to measure the absolute value of VTM elements and show that the randomness of the medium can be used as a resource in controlling the phase, …

Flexible Strain Detection Using Surface Acoustic Waves: Fabrication and Tests
… of polyvinylidene fluoride (PVDF) as a polymer matrix, with lead zirconate titanate (PZT), calcium copper titanate (CCTO), and carbon nanotubes (CNTs) as micro and nanofillers’ structural, thermal and electrical properties are investigated. Piezoelectric property measurements are carried out for …

Holographic Control of Light Propagation in Optical Waveguides
… medium. As such, it can be characterised by its transmission matrix, allowing complex light fields to be imaged and projected through the fibre. Control over light at the fibre tip and along a fibre taper are demonstrated. I present a quantitative comparison between different algorithms for the …

A new generic maximum-likelihood metric expression for space-time block codes with applications to decoding
… explicitly maintains the redundancy in the STBC transmission matrix. By expressing the ML metric using the new vectorization, a new generic representation of the ML metric expression for a linear STBC is derived. One immediate application of this new metric expression is the convenient partial …

Theoretical and numerical study of nanostructures
… systems with complex geometry including transmission matrix methods, mode matching, and tight binding Green's function techniques such as the one used by Sols et al. in the study of the quantum modulated transistor. NPDX, however, permits the study of mesoscopic structures where other …

Analysis and measurement of anti-reciprocal systems
… coefficient Ta(s) are calculated using transmission and impedance matrix methods. The model has been verified with electrical input impedance, diaphragm velocity in vacuo, and output pressure measurements. This receiver model is suitable for designing most electromagnetic transducers, …

Contribución al análisis y procesado de señales fotónicas multibanda
… After that, we present the method based on transmission matrix developed by our group in collaboration with the group of the Universidad Politécnica de Valencia. In addition, we present a subsampling method for multilayer systems. These tools decrease dramatically the computation time in the …
