0 a wave moving through a substance in which the particles are vibrating (= moving quickly backwards and forwards) at a 90 degree angle to the direction of the wave -- 横波，横向波
Here we are concerned with how the spectrum of the linearized operator depends upon the transverse wave number.
Since the simplified approach does not include the transverse wave system, it should be used where the diverging wave system is dominating.
The chain line is for the amplitude of the stable transverse wave response for which the interaction between resonant longitudinal and transverse waves is included.
The character of field distribution in the cross section for the waveguide is determined by the transverse wave numbers.
Each of these fields, the electric and the magnetic, exhibits two-dimensional transverse wave behavior, just like the waves on a string.
A transverse wave is one in which the amplitude vector is orthogonal to k, which is the case for electromagnetic waves in an isotropic medium.
Light is an example of a transverse wave.
However, a transverse wave apparently required the propagating medium to behave as a solid, as opposed to a gas or fluid.
