Therefore, the modal shape of the cylindrical shell can be determined by any combination of the axial half-wave number m and the circumferential wave number n . WebWhen m = 0, and n = 1, the microwave wave number distributed along the circumference of the TE01 mode is 0, and the microwave wave number distributed along the radius is 1. Therefore, the TE01 mode has circular symmetry in the circumferential direction, the loss in the circumferential direction is the smallest, and loss is the smallest near the ... bolton edwards elementary school
