When propagating inside of a hollow, rectangular perfect conductor, these phenomena propagate in TE or TM modes. For 10 points each:
[10e] Name these phenomena that are transverse when the direction of disturbance is perpendicular to their propagation.
ANSWER: waves [accept electromagnetic waves]
[10h] This mode is the lowest allowable TE, or transverse electric, mode for a hollow rectangular waveguide made with a perfect conductor.
ANSWER: TE10 (“T-E-one-zero”) mode
[10m] Each pair of indices of a rectangular waveguide with side lengths a and b determines a value for this quantity computed as “c, times pi, times the square root of the following: m over a squared, plus n over b squared.” Below this quantity, the solutions for the E- and B-fields indicate exponential attenuation rather than traveling waves.
ANSWER: cutoff frequency [accept corner frequency or break frequency; prompt on cutoff or frequency; reject “cutoff wavelength”]
