Let's consider a rectangular wave guide with dimensions of ? =
1.58 cm and ? = 0.79 cm, filled with air inside and copper
outside.
a) Calculate the cutoff frequency for the first three advancing
modes. Specify the name of the
dominant (basic) mode.
b) Draw roughly the electric field and magnetic field lines in
the waveguide sections (sections taken from the xy, yz and xz
planes) for the basic mode. For drawing, consider that the
waveguide extends in the...
A hollow waveguide has dimensions a = 1.5cm and b = 0.8cm. the
guide is operating in TE10 mode. The operating frequency (f) is
12GHz. If the component in z for the magnetic field is given
by:
H_z = 5 * cos? ((?/a) x) *cos? (wt-?z)
a) Determine expressions in the time domain of the transverse
electric fields (Ex, Ey). substitute any variable in the expression
with its values (i.e. ?, ?, k_c, a, b, etc.).
b) Determine the maximum...
A sound wave has a propagation speed of 349 m/s, a frequency
1026 Hz, and has a maximum displacement of ym=
3.02x10-7 m. At time t= 0, and x= 0, the displacement is
ym = 1.00x10-7 m.
(a) Using these values, find an equation of form:
y(x,t) =
ym sin(kx - ωt + ϕ)
(b) Differentiate the expression and find the maximum speed of
the oscillating air molecules.
(c) Find the maximum magnitude of acceleration of the...

A rectangular channel of bottom width B = 7 m carries an average
discharge of Q = 8 m3/s. There are two successive long
reaches. The first reach has s01=0.015 and
n1=0.010; and the second reach has s02=0.0017
and n2=0.021. Classify the slopes.

Given two arrays: A[0..m-1] and
B[0..n-1]. Find whether B[] is a subset of A[] or not. Both the
arrays are not in sorted order. It may be assumed that elements in
both array are distinct. Design an O(n) time algorithm that solves
this problem. Provide pseudocode
Ex:
Input: A[] = {11, 1, 13, 21, 3, 7}, B[] = {11, 3, 7, 1}
Output: B[] is a subset of A[]
Input: A[] = {1, 2, 3, 4, 5, 6}, B[] =...
