Question 1 If an electromagnetic wave described by the TE20 mode is excited and is propagating down the waveguide, what happens to the electromagnetic wave described by the TE10 mode? Question 2 Is Kz (the direction of propagation down the waveguide) solely dependent on the cross section of the guiding structure? Question 3 We learn in the TEM discussion that a center conductor is needed to support a TEM wave. Otherwise, only TE or TM waves can propagate down the wave guide. Consider a waveguide (for example, a circular length of pipe) and suppose we shine something like a laser beam down the waveguide. Is a TEM wave going from one end of the waveguide to the other? How do you reconcile this seemingly contradictory statements?
A cylindrical conductor of radius b is solid, except for a hole of radius a, bored down the z axis. Uniform current I flows in the positive z direction. a) Using Ampere's circuital law, find the magnetic field strength
How to design the logic circuit for a room has three doors, with aswitch next to each door, and one over head light. A person shouldbe able to enter or exit from any door and turn the room light onor off by toggling the switch.
a small cocentration of minority carrier is injected into ahomogeneous semiconductor crystal at one point. An electric feild of 10 V/cm is applied across the crystal and this moves theminority carriers a distance of 1cm in 20μsec.
In a circuit, the generator voltage varies in time, where the amplitude of e max= 1.2 volt and emf freq.= 0.5 Hz , which the max current is equal to the max current when the freq. of emf = 3.0 Hz, which is .00033 A.
(a)Determine the capacitance of an isolated conducting sphere of radius a in free space (Consider an outer conductor existing at r -> infinity). (b) The sphere is to be covered with a dielectric layer of thickness d and have a dielectric constant o..
Assume dual rail logic. Dual rail logic means that both a variable and its complement are available as inputs to the logic block, such that an inverter is not needed to generate B' from B.
A parallel plate capacitor is made of plates in the shape of equilateral triangles with sides of length 15 mm. The plates are separated by titania ceramic of thickness 1.55*10^-6m. What is the capacitance
A solar heating system can recharge (store heat) in a single sunny day enough to provide for the next two days. In otherwords, the only times that the solar heat must be augmented by someother heat source is when there are three of more consecutiv..
Consider a system equation s^4 + s^3 + s^2 + 2s + 10 = 0. FInd out its Routh Table. Determine if this system is stable, marginal stable or unstable. How many roots are stable and how many roots are unstable.
What is Intermediate switch, its construction, working principle and uses in different wiring (lighting etc) circuits?
Impulse Responses of LTI systems can be physically found by inputting \(x[n] = \delta[n]\)to the system and measuring the output. Assume that during the process, we inadvertently input\(x[n] = \delta[n] + \delta[n-1]\)
On any given day, the price of stock XX can do one of three things: jump very high, fall very low, or stay reasonably close to its opening value. You are trying to use Bayes' Law to determine if stock XX is being bought or sold by shareholders
