The phrase "a fundamental mode" is correct and usable in written English.
It can be used in contexts discussing basic or essential methods, approaches, or states in various fields such as science, philosophy, or technology.
Example: "In quantum mechanics, a fundamental mode of vibration can determine the energy levels of a system."
Alternatives: "a basic mode" or "an essential mode".
The front-loaded backstory of "Fantastic Four" isn't, in itself, a problem of dramatic construction; it's a fundamental mode of experience, albeit one that's repeatedly undercut by the distracting antics of the movie's bureaucratic villain and the needless plot mechanisms that come in his wake.
Play is not only our creative drive; it is a fundamental mode of learning (Wood, 2004).
As the name indicates, HT is a sustained oscillation consisting of a fundamental mode and its overtones.
A fundamental mode at λFU= 1.55μm, and a copropagating second harmonic mode at λSH= 0.775μm are considered.
The resonator, 2 mm long and 0.52 mm wide, resonates in air and has a fundamental mode at 56.5 kHz with a Q-factor of 70.
As a fundamental mode is introduced in the input SMW, at certain frequencies, the SMRW modes are enhanced because of resonance and the light-waves are coupled to the output SMW.
At room temperature, Design A at the fundamental mode had a Q substantially higher than another resonator of the same size but different support design (referred to as Design B in this work: 9500 compared to 2400).
Measured values of Q were much lower than Design A at the fundamental mode, and Q likewise did not increase with cryogenic cooling to 78 K.
This spectrum involves some assumptions including a liner fundamental mode shape, negligible aerodynamic damping, and a power law profile of the mean wind speed and turbulence intensity.
A large mode area multicore photonic crystal fiber with a flattened fundamental mode is proposed in this paper.
An energy of 100 mJ with 23% slope efficiency in a near fundamental mode was achieved in the free-running regime.
