Precise measurements of optical constants of SiC in 40 to 120 µm wavelength region
2010 Edition, September 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Optical constants of 6H-SiC have been measured by using far infrared (FIR) lasers of 48, 57, 71, and 119 µm in wavelength. The refractive index and absorption coefficient at the wavelength have been determined from the transmittance...

Precise measurement of optical constants of Si for short-wavelength far-infrared region
2004 Edition, January 1, 2004 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Powerful short-wavelength far-infrared lasers (/spl lambda/=40 /spl mu/m-100 /spl mu/m) and the measurement system are developing for plasma diagnostics (NIFS) and a /spl lambda/ ray production (JASRI). In the wavelength region, the choice of...

Precise Measurements of Electromagnetic Fields
1938 Edition, Volume 26, January 1, 1938 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A design of field strength measuring equipment is described wherein the emphasis has been laid upon ability to secure precise measurements in a limited range rather than extreme flexibility. A consideration of the suitability of various fundamental...

Precise measurement of complicated frequency signals
2015 Edition, April 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Based on the border effect and relevant theories, it is found that measurement precision depends on resolution stability which is much higher than resolution itself. With the help of this new theory and the more sensitive discrimination of the border of a fuzzy area, it...

System identification with mixed binary-valued and precise measurements
2017 Edition, October 1, 2017 - Institute of Control, Robotics and Systems (ICROS)

This paper considers system identification based on mixed binary-valued and precise measurements with noises. The optimal Quasi-Convex Combination Estimator (QCCE) is constructed by combining the identification results of binary-valued and precise subsystems. The...

Sharp edges and precise measurements
1985 Edition, September 1, 1985 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Practical electrodes may have rounded or diffuse edges, but their counterparts used in modelling have well defined sharp edges. We show the effect of the high field at the sharp edge in three situations: (a) an improved computation of the edge capacitance of strip...

Precise measurement method for high frequency dielectrics
1990 Edition, January 1, 1990 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The precise measurement methods for dielectric materials are described. Improvements both in accuracy and speed are described for the technique of measuring the microwave dielectric properties of low-loss materials by dielectric rod resonators placed between two...

A precise measurement of QHR in NIM
1990 Edition, January 1, 1990 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Equipment for the precise measurement of quantized Hall resistance (QHR) is described. The essential components of this equipment are a resistance comparator of one to one ratio with a comparison uncertainty of 3*10/sup -8/ and two specially designed...

Optical constants of anisotropic and absorptive liquids
2002 Edition, January 1, 2002 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Optical constants, /spl radic//spl epsiv/=n-jk, of the anisotropic and absorptive liquids, i.e., liquid crystal and magnetic fluid, were evaluated by reflectometry in the visible and infrared spectral regions. Semicylindrical prisms were prepared with high-index glass or...

Optical constants of InP and GaP
2000 Edition, Volume 1, January 1, 2000 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Calculation of the optical constants of InP and GaP is presented. The employed model is a modification of Adachi's model of the optical constants of semiconductors, which employs adjustable broadening instead of the conventional...
