We have imaged mitochondrial oxidation–reduction states by taking a ratio of mitochondrial fluorophores: NADH (reduced nicotinamide adenine dinucleotide) to Fp (oxidized flavoprotein). Although NADH has been investigated for tissue metabolic state

We propose, develop, and implement an exact method to analyze the scattering of chiral periodic structure. The method combines the building block approach of multimode network theory with a rigorous mode-matching procedure. Symmetry properties of the

We introduce a new model of the generation of pre-seismic electromagnetic emissions, which explains the observed phenomenology in terms of its geometry and fractal electrodynamics. Accumulated evidence indicates that an earthquake can be viewed as a

Fractal superlattices are designed by alternating dielectric layers according to an iterative fractal process. The discrete self-similarity of such stratified structures can be remotely detected from interrogation by an incident pulse. In this paper,

Multi-gap superlattices having the same fractal (similarity) dimension may differ in their distribution of gap sizes. This distribution is characterized by a fractal descriptor denoted the lacunarity. From the wavelet analysis of the superlattice's i

We use fractals to design a class of Cantor ring arrays — both continuous and discrete. Using dimension, lacunarity, stage of growth and other fractal descriptors, we find relevant connections between fractal geometry and array performance includin

Angular scattering from radially stratified spherical chiral objects is investigated. Based on the principles of invariant embedding, we formulate a matrix Riccati equation that can be used to examine basic scattering properties of spherical chiral s

We use the impedance method to study the far-field diffraction of a transmission grating characterized by a Cantor density function. This density function is obtained from a multiplicative superposition of periodic functions. Intensity patterns for d

The contributions of this book represent only a small sample of the work of the many researcher electromagneticians who have had the pleasure of being associated with Professor Papas, either as students or as colleagues. Many of us continue to work i
