A thin slot. Create a 2D TM mode simulation that is 100 × 200 grid cells, designed for a frequency of 300 MHz. Place a vertical "wall" of PEC material across the center of the simulation space, but with a hole in the center of a few grid cells. Excite the simulation with an z source to the left of the wall, and measure the field intensity that leaks through the hole. Vary the size of the hole from 20 down to one grid cell; how does the field intensity to the right of the wall depend on the hole size? Can you think of a way to do this simulation with a hole that is less than one grid cell wide? We will revisit this problem in Chapter 12.
Determine which of these properties hold and which do not hold for each of the following continuous-time systems. Justify your answers. In each example, y(t) denotes the system output and x(t) is the system input.
Determine the total number of possibilities, and ask the user to identify the configuration and provide the capacitor values. Then calculate the total capacitance.
An electric field in free space is given as E=(x,4z,4). Given VA=10v, calculate the electric potential difference VAB & VB, where A is (1,1,1) and B is (3,3,3), assuming V=9 at (2,4,6).
What is the Role of Capacitor in AC and DC Circuit? and what is his Capacitance Equation ?
Contrast the electron and hole drift velocities through a 10 um (micro meter) layer of intrinsic silicon across which a voltage of 5V is imposed. Let up = 480cm2/Vs and un=1350cm2/Vs.
Determine if the following CT signal is periodic. calculate the fundamental period T0 for the CT signal: x(t) = 2cos(4*pi*t/5)*sin^2(16t/3)
desgin a four-bit combinational circuit 2's complenmter.(the output generate complement of the input binary). then construct truth table for the input and correspondinf output. use kmap to find each outpt in terms of of inputs.
In the "far field" region, show that the electric field intensity of a linear electric quadrupole decays much faster in space than 1/R3 for the electric field intensity produced by an electric dipole and 1/R2 for an electric monopole.
