Refractive index

View this topic in
The refractive index or index of refraction of a substance is a measure of the speed of light in that substance. It is expressed as a ratio of the speed of light in vacuum relative to that in the considered medium. (Wikipedia.org)

Evaluating the potential shielding properties of periodic metamaterial slabs

Divitha Seetharamdoo; Marion Berbineau; Anne-Claude Tarot; Kouroch Mahdjoubi 2009 International Symposium on Electromagnetic Compatibility - EMC Europe, 2009

Metamaterials can prove to be good candidates for shields in EMC applications where weight reduction is a challenge. Indeed metamaterial slabs can provide the same reflective properties as conventional metallic screens but with a lower density and reduced weight. Another advantage is that they can be tailored to exhibit required frequency-selective properties. However, their performance in terms of shielding performance ...


Integrated Nonmagnetic Optical Isolators Based on Photonic Transitions<formula formulatype="inline"> <tex Notation="TeX">$^{ast}$</tex></formula>

Zongfu Yu; Shanhui Fan IEEE Journal of Selected Topics in Quantum Electronics, 2010

Based on the effects of photonic transitions, here we show that a linear, broadband, and nonreciprocal isolator can be accomplished by spatial-temporal refractive index modulations that simultaneously impart frequency and wave vector shifts during the photonic transition process. This paper demonstrates that on-chip isolation can be accomplished with dynamic photonic structures in standard material systems that are widely used for ...


Exact Efficiency Evaluation in Loaded Diffused Optical Waveguide Modulators

V. Andresciani; M. N. Armenise; M. De Sario 1977 7th European Microwave Conference, 1977

In this paper, we consider an overlayed erfc diffused LiNbO3 ferroelectric crystal in order to design a planar-type modulator by the mode conversion method. The multilayer structure is analysed into two configurations; in the first the optical axis is perpendicular to the electrode plane, in the second is parallel. In both cases the effects on the coupling coefficient of the ...


Origin of Birefringence in Wood at Terahertz Frequencies

Tara M. Todoruk; Ian D. Hartley; Matthew E. Reid IEEE Transactions on Terahertz Science and Technology, 2012

In the wood products industry, terahertz (THz) radiation is showing promise for new types of sensing and imaging applications, which depend on the ability of THz radiation to probe the gross fiber structure of wood. The sensitivity to this gross fiber structure is a result of the strong birefringence of wood at THz frequencies. Wood is a complex structure, and ...


Linearization of a broadband analog optical link using multiple wavelengths

E. I. Ackerman International Topical Meeting on Microwave Photonics. Technical Digest (including High Speed Photonics Components Workshop) (Cat. No.98EX181), 1998

Instead of balancing the RF signal voltage on two modulator electrodes, broadband linearization of a link can be more easily achieved when two wavelengths are simultaneously modulated using a standard single-electrode Mach-Zehnder modulator.

    Learn about the revolutionary new technology of negative-refraction metamaterials Negative-Refraction Metamaterials: Fundamental Principles and Applications introduces artificial materials that support the unusual electromagnetic property of negative refraction. Readers will discover several classes of negative-refraction materials along with their exciting, groundbreaking applications, such as lenses and antennas, imaging with super- resolution, microwave devices, dispersion-compensating interconnects, radar, and defense. The book begins with a chapter describing the fundamentals of isotropic metamaterials in which a negative index of refraction is defined. In the following chapters, the text builds on the fundamentals by describing a range of useful microwave devices and antennas. Next, a broad spectrum of exciting new research and emerging applications is examined, including: * Theory and experiments behind a super-resolving, negative-refractive-index transmission-line lens * 3-D transmission-line metamaterials with a negative refractive index * Numerical simulation studies of negative refraction of Gaussian beams and associated focusing phenomena * Unique advantages and theory of shaped lenses made of negative-refractive-index metamaterials * A new type of transmission-line metamaterial that is anisotropic and supports the formation of sharp steerable beams (resonance cones) * Implementations of negative-refraction metamaterials at optical frequencies * Unusual propagation phenomena in metallic waveguides partially filled with negative-refractive- index metamaterials * Metamaterials in which the refractive index and the underlying group velocity are both negative This work brings together the best minds in this cutting-edge field. It is fascinating reading for scie ntists, engineers, and graduate-level students in physics, chemistry, materials science, photonics, and electrical engineering.

    Many extraction methods for approximately determining the electrical properties of a meta-material slab have been developed; however, they are subject to certain limitations. In this chapter, the phase and dispersion relations of a periodic medium will be taken into account for obtaining the effective refractive index of a medium with respect to an arbitrary incident condition.
