On the other hand, bare mode coupling coefficients cannot be directly computed in our approach.
In the second mode, the largest coupling coefficient of 6.05% associated with a phase velocity of 6234 m/s and a TCD of 20.9 ppm/°C can be found; for a zero TCD case, a large coupling coefficient of 5.35% associated with a phase velocity of 6460 m/s can be obtained.
Results show that the second mode (Sezawa mode) exhibits the largest coupling coefficient.
Results show that the mode 1 (Sezawa mode) exhibits the largest coupling coefficient of 1.28% associated with a phase velocity of 9500 m/s.
In order to attain high efficiency and stable radiation, TE31,12 mode that lies in a relative sparse spectrum is selected as the operating mode and the beam-wave coupling coefficient, and start oscillation current are calculated by a set of source codes.
Using a conformal mapping technique we obtain an expression for the characteristic mode impedances and coupling coefficients of an asymmetric multi-conductor transmission line.
The A0 mode phase velocity and the electromechanical coupling coefficient (K2) dispersion curves were theoretically studied for four different electroacoustic coupling configurations.
where the forward rotation mode of resonators is denoted as a1 and a2 whose second norm has energy dimension; ω1,2 are natural resonant angular frequency; κ12 and κ21 are mode coupling factors; and there is a relationship with coupling coefficient k which is κ = ωk/2.
It is shown that power exchange of the two modes is determined by the internal coupling coefficient.
The realization of the strong coupling interaction relies on the condition that the coupling coefficient between the nanocavity mode and the quantum dot exceeds the intrinsic decay rate of the nanocavity [17].
