A dielectric slab waveguide is made from two materials of respective refractive index 1.51 and 1.50. What thickness should the core be in order for the first higher order mode cut-off ; wavelength to be 1 pm? Sketch the field distribution of the fundamental and the first higher order mode for the above case.
The effective index of the fundamental TE mode is 1.505 at an operating wavelength of 1 μm. What is the normalized amplitude of the electric field at the core boundary?
The total friction and core losses may be assumed to be constant at 403 Watts, independent of load. For a slip of 2% , compute the speed, output torque, and power and stator current, power factor and efficiency when the motor is operated at rated ..
Given that the capacitance of the plates is 4 nF, sketch the current flowing through the plates.
In maximum power transfer problems, how do you determine whether the Thevenin voltage is expressed in terms of its maximum amplitude or its rms amplitude
write a program that would send out through the serial port an array of twenty bytes of data( need a FOR loop) stored in memory locations starting from 30H( must use a ponter) with even parity added as the ninth bit.( skip baud rate).
