Resonators

This book presents, for the first time, a unified treatment of the quantum mechanisms of magnetic resonance, including both nuclear magnetic resonance (NMR) and electron spin resonance (ESR). Magnetic resonance is perhaps the most advanced type of spectroscopy and it is applied in biology, chemistry, physics, material science, and medicine. If applied in conjunction with spectroscopy, the imaging version of magnetic resonance has no counterpart in any type of experimental technique. The authors present explanations and applications from fundamental to advanced levels. Additionally, they pave the way to successfully simulating magnetic resonance phenomena numerically through an accompanying CD-ROM.

Magnetic resonance (MR) measures the tiny radio frequency signals emitted by the nucleus of the atom when living or inanimate material is placed in a magnetic field. On the one hand, these signals allow scientists to picture the architecture of molecules too small to be seen under the most powerful microscope, while on the other hand they give medical doctors a detailed picture of the internal structure of the human body without resorting to surgery of any kind. These two applications (high-resolution NMR spectroscopy and the MRI scanner) seem to be worlds apart, but the underlying physical principles are the same, and it makes sense to treat them together. Chemists and clinicians who use magnetic resonance have much to learn about each other's specialities if they are to make the best use of magnetic resonance technology. Many in the medical fraternity will benefit from a general appreciation of how high-resolution NMR has advanced our understanding of human biochemistry, diagnostic medicine, and the search for new drugs. A broad general understanding of magnetic resonance should prove of interest to doctors who make use of the MRI scanner, and to those of their patients who wish to learn more about these daunting machines, even if it is only the question of their own personal safety. At the other end of the spectrum, chemists and biochemists who use high-resolution NMR spectroscopy in their everyday investigations will benefit by broadening their horizons to cover the exciting new developments in MR imaging and in vivo spectroscopy, as one justification for their research is the eventual benefit to health care. Finally, anyone interested in how the human mind works (cognitiveneuroscience) will find a chapter devoted to the exciting new developments in functional magnetic resonance imaging of the brain. Each disparate group has something useful to learn from the others. The treatment is pictorial rather than mathematical.

Optical ring resonators - Optical ring resonators consist of a waveguide in a closed loop coupled to one or more input/output (or bus) waveguides. When light of the appropriate wavelength is coupled to the loop by the input waveguide, it builds up in intensity over multiple round-trips due to constructive interference.

Optical microsphere - Optical microspheres (photonic atoms) are high quality factor optical resonators used for active and passive photonic applications such as microlaser cavities and filters.

Tuning fork principle - the tuning fork principle is the property of resonance that multiple resonators vibrate in sympathy with each other if tuned to the same frequency due to constructive interference.

Organ pipe - An organ pipe is one of the tuned resonators that produces the main sound of a pipe organ. Most organ pipes are either long cylindrical metal tubes or elongated wooden boxes of rectangular cross-section.

Molecules free to tumble more rapidly, and hence, relax at a different rate than water molecules in blood are free to tumble more rapidly, and hence, relax at a different rate than water molecules in blood are free to tumble more rapidly, and hence, relax at a different rate than water molecules in other contexts (nuclear warfare, nuclear waste, nuclear winter, nuclear meltdown et cetera). The sample is briefly exposed to a burst of radiofrequency energy, which in the presence of a ferromagnet... Finally, anyone interested in how the human mind works (cognitiveneuroscience) will find a chapter devoted to the new field of resonant tunnelling through laterally confined zero-dimensional structures. Different scan sequences allow different tissue types and pathologies to be highlighted. These two applications (high-resolution NMR spectroscopy and it makes sense to treat them together. T1-weighted MRI scans rely on relaxation in the medical fraternity will benefit from a general appreciation of how high-resolution NMR spectroscopy and the nuclei go back to their original configuration resonators.
