Sr No | $TE_{mn}$ | $TM_{mn}$ |
---|---|---|
1 | It is Transverse electric mode | It is transverse magnetic mode |
2 | Ez=0 that means energy transmission is done by Hz. | Hz=0 that means energy transmission is done by Ez |
3 | Dominant mode is TE01 mode | Dominant mode is TE11 mode |
4 | Cutoff frequency of dominant mode is less than TE11 mode | Cutoff frequency of dominant mode is more than TE10 mode |
5 | TE01 and TE10 mode exist | TM01 and TM10 mode does not exist |
6 | Cutoff wavelength for dominant mode=2a | Cutoff wavelength for dominant mode= $2ab{\sqrt{({{a})^2}+ ({{b}})^2}}$ |
