Design a circular waveguide field with a lossless non-magnetic dielectric medium. The waveguide must operate in a single mode over a bandwidth of 1.5 GHz. The radius of the guide is 1.12 cm. (a) Find the relative permitivity of the medium that filled the waveguide.
(b) Find the lower and upper frequencies of the operation.

How do you solve a question like this?

1) what is the measure of the exterior angle, ∠uvw ? 2) in triangle man, what is the measure of the exterior angle at n (in degrees)?

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18}, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. assume that each outcome is equally likely. list the outcomes in f or g. find p(f or g) by counting the number of outcomes in f or g. determine p(f or g) using the general addition rule.
