QUIZ ONE Answer with true or false and correct the false ? a - The signal X(t) is said an even signal if it satisfied the condition X(t) = -X(t) for all t. b- Random signal is the signal that changes randomly with time therefore can be represented mathematically. C--Power signal has infinite power, but its energy is finite. d- Energy signal has infinite energy, while power is zero. e- If f(t+ T/2) = f(t) only odd harmonics are present ,while f( t+T/2) = - f(t) only even harmonic are present.

Write your own code to solve the transcendental equation for a symmetric slab waveguide in terms of normalized parameters. Show that the code works for a variety of thicknesses, index contrasts and wavelengths (a few each). Matlab will use fzero function, while in Python it is fsolve. Alternatively, the code can look for the intersection of 2 curves graphically.
