The phrase "a fundamental wave" is correct and usable in written English.
It can be used in contexts related to physics, particularly in discussions about wave theory or the nature of waves in various mediums.
Example: "In quantum mechanics, a fundamental wave can represent the basic state of a particle's wave function."
Alternatives: "a basic wave" or "a primary wave".
a Ratio of fundamental wave to total energy.
From Eq. (5), we can find that A-phase winding MMF after the Fourier series transformation can be decomposed into fundamental wave and a series of higher harmonics, and the amplitudes of fundamental wave and higher harmonics pulse over time with the current frequency.
In this paper, we describe propagation of very low frequency (1 10 to 100 Hz) Stoneley waves in a fluid-filled wellbore and their interactions with the fundamental wave mode in a vertical hydrofracture.
The fundamental wave has a peak intensity between 0.4 and 4 Hz whose frequency is defined as f peak(nh = 1), where nh represents the number of harmonics.
Based on measured fundamental wave and SHG peak powers, the introduction of a Ag nanocavity increased the conversion efficiency of the NWs ~ 300-fold (Fig. 6d).
In the nonlocal analysis, at higher values of the y-directional wavenumber, a decrease in the frequency band gap is observed for all the three fundamental wave modes in the graphene silicon system.
This can be achieved in the proposed photonic crystal fiber because the sum-frequency wave propagating in a LP02 mode leaks more into the low refractive index cladding than does the fundamental wave.
Since the nonlinear optical response strongly depends on the interaction between fields of fundamental wave and nonlinear materials, designing high quality optical cavities has been a key strategy to achieve improved nonlinear activities.
According to the instantaneous power detection method, i αL t) is multiplied by the voltage synchronization signal, and then the half of the fundamental wave active current amplitude can be extracted from its product by a low-pass filter, namely, ( sqrt 2 /2{text{I}}_{alpha {text{p}}} ).
