har·mon·ic

(har-mon'ik),
A component of complex sound, the frequency of which is a multiple of the fundamental frequency, which is also called the first harmonic; the second harmonic has twice the frequency of the fundamental, and so forth.

harmonic

In physics, concerning wave forms, an oscillation or frequency that is a whole number multiple of the basic frequency.

I think that residents need to gain expertise with the traditional method, but once they're proficient, I feel comfortable teaching them to use the HARMONIC WAVE device.
dagger]) Notice, from another different perspective, that for vey large air gaps (more precisely: when air gap length and pole pitch of the harmonic wave are of similar order), the errors in determining the air gap B values become completely unacceptable, as shown, especially, in Fig.
The aim of the analysis is to find scattering parameters of the investigated structure assuming arbitrary incidence angle of the harmonic wave illuminating FSS.

In order to characterize power components, a power measurement system is required, which can be used to adjust the fundamental and harmonic waves to active loads by up to 40 GHz ("Active Load Pull").
His topics include elastic solids in series and parallel, Bernoulli's equation, through the Earth and back, impedance and power, the linear superposition of right-moving harmonic waves, through a glass darkly, convective and conductive heat flow, thermodynamic cycles and heat engines, and the canonical ensemble.
In addition to the traditional problems of interference of coherent harmonic waves the interference of pulses is also considered.
In order to evaluate the quality of single data points, oscillatory raw data can be analysed by Lissajous figures and higher harmonic waves.
The actuators are driven in a closed feed forward control loop, which means that multiple order harmonic waves are cancelled even when engine speeds change very quickly.
This phenomenon could be described similarly to a sum of two or more harmonic waves having nearly equal frequencies.
Application of transformation of ABP and ICP slow harmonic waves into rect(t) type signals is at the first time proposed in this work for elimination of PRx(t) non-linear distortions.
