角度(degree)和弧度(radian)的区别

我不确定你在问什么，但是'degree'可以指角度，而'radian'可以指弧度。

Calculated PBG of the dielectric multilayer chip. K0 is the wavenumber and β0 is the propagation constant. The allowable bands and the photonic forbidden bands of this chip are marked in yellow and dark blue, respectively. The solid magenta line represents the light line in air. The solid cyan line represents the dispersion curve of the BSW mode.
