This is the case for all linear elements, but also, for example, an ideal diode, which in circuit theory terms is a non-linear resistor, has a constitutive relation of the form = (). Both independent voltage and independent current sources can be considered non-linear resistors under this definition.
A bumblebee with a transponder acting as a non-linear junction for tracking the animal by way of harmonic radar.. The non-linear junction detector, or an NLJD, is a device that illuminates a small region of space with high-frequency RF energy.
[1] [2] This deviation from linearity is described as the non-linear effect, NLE. [3] The linearity can be expressed mathematically , as shown in Equation 1. Stereoselection (i.e. the ee product ) that is higher or lower than the enantiomeric excess of the catalyst (ee catalyst , relative to the equation) is considered non-routine behavior.
Historically, linear analog filter design has evolved through three major approaches. The oldest designs are simple circuits where the main design criterion was the Q factor of the circuit. This reflected the radio receiver application of filtering as Q was a measure of the frequency selectivity of a tuning circuit.
E-Material, also called E Material, is a metal matrix composite consisting of beryllium matrix with beryllium oxide particles. It has high thermal conductivity (210-230 W/m K), and its thermal expansion can be adjusted to match other materials, e.g. silicon and gallium arsenide chips and various ceramics .
Current to voltage converters are used with sensors that have a current response that is more linear than the voltage response. This is the case with photodiodes where it is not uncommon for the current response to have better than 1% nonlinearity over a wide range of light input. The transimpedance amplifier presents a low impedance to the ...
Nonlinear optics (NLO) is the branch of optics that describes the behaviour of light in nonlinear media, that is, media in which the polarization density P responds non-linearly to the electric field E of the light. The non-linearity is typically observed only at very high light intensities (when the electric field of the light is >10 8 V/m and ...
Sub-diffraction limit for non-linear metamaterial lens [ edit ] By covering a thin flat nonlinear lens on the sources, the sub-diffraction-limit observation can be achieved by measuring either the near-field distribution or the far-field radiation of the sources at the harmonic frequencies and calculating the IFT to obtain the sub-wavelength ...
