When the directions of M and k are identical and both lie in the plane of the film, the spin wave is called the backward volume magnetostatic mode (BWVMS).

Simulating of the energies of magnetic fields made for a steady state in magnetostatic mode, skin and proximity effect is neglected.
The magnetostatic modes generated in the planar transmission line system are analyzed using coupled mode theory [10].
In the presence of external dc magnetic field two magnetostatic modes are produced one at the ferrite-air interface and the second mode is concentrated near the ferrite-metal interface [29].
The angles where the phase matching between the magnetostatic modes and TEM mode occurs, gives the maximum coupling [10, 30].
Good cutoff behaviour of more than 28 dB is observed over the external magnetic field range from 40 G to 250 G and is caused by coupling between TEM and magnetostatic modes.
Further size reduction is difficult since the tuning magnetic field must be uniform to prevent generation of out-of-band and inband spurious signals due to magnetostatic modes. In addition, as the size is reduced, assembly of the YIG spheres and wire coupling loops (Figure 1a) will become more difficult and costly.
Excessive increase of loop coupling can cause crossing of the magnetostatic modes into the passband at some frequencies and distorting the phase linearity.
