yes it can have coz fc= c/2[(m/a)2+(n/b)2]1/2
therefore for various modes(which decide m,n) nd dimensions(a,b) of waveguide it will have different cut off frequency.
A normal waveguide is used in the octave frequency range where only the fundamental mode can propagate.

Why the te0 mode is the dominant mode in rectangular waveguide?
Because it has the lowest cut-off frequency (highest cut off wavelength) for a>b o
What is alpha cut of frequency?
it is the frequency at which the current amplification drops 3dB below its low frequency value.
How High pass filter circuits works?
A High Pass Filter is an Electronic Filter that passes high frequency signals but Attenuates (reduces the Amplitude ) of Signals with frequencies lower than the cut-off Frequency
What is meant by beta cutoff frequency?
The beta cut off frequency is the frequency at which the current amplification of an amplifier transistor drops to three decibels below its value at 1 kilohertz. This is used in electronic engineering.
Relation between cutoff frequency and bandwidth?
The relation between cut off frequency (fc) and band width is as follows: fc=Q*B.W where Q=(fL*fH)^1/2/(fH-fL) Q is quality factor. fL is low frequency. fH is high frequency.

Is a high pass filter and a low pass filter the same thing?
Yes, they are both filters. But their frequency characteristics are different. This is the main reason why they are given different names. A high-pass filter passes frequencies higher than its cut-off frequency, and stops those that are lower. A low-pass filter passes frequencies lower than its cut-off frequency, and stops those that are higher.
What has the author D H Sinnott written?
D. H. Sinnott has written: 'The computation of waveguide fields and cut-off frequencies using finite difference techniques'
Are cut or uncut rubies worth more?
Uncut rubies are worth more than cut rubies
What are the application of low pass and high pass filter?
they are used in industries so to able you to work on particular frequency and cut the other for e.g if you are working for high frequency then low frequency will be cut and vise versa
How High pass filter circuits works?
A High Pass Filter is an Electronic Filter that passes high frequency signals but Attenuates (reduces the Amplitude ) of Signals with frequencies lower than the cut-off Frequency
Can a diamond or gemstone be cut more than once?
Yes.
Is it more dangerous to cut a vein or artery and why?
An artery because blood is pumped through the arteries at a much higher pressure than the veins. Therefore if you cut an artery you will lose a lot more blood a lot quicker than if you cut a vein.
Why don't we say hairs cut?
Getting your hair cut implies that it is more than one strand of hair has been cut. Therefore, hairs cut is not used.
Why are Crinkle Cut McCain Home Fries more expensive than straight cut?
Because they are harder to make
What makes the princess cut sets better than the others?
A princess cut diamond is said to sparkle more.
