There exists a large difference in the line width of uniform resonance estimated for various ferrites by making use of our simplified model of ferrimagnetism.

Smoothing, dense and uniform nano crystalline diamond like carbon films are prepared by using electron cyclotron resonance (ECR) microwave acetone plasma chemical vapor deposition (CVD) method.

Compared with that with uniform period, the reflectivity of Gaussian profile grating with nonuniform period has almost no resonance side lobes at shorter wavelength.
