How to plot reflection phase diagram of an ebg structure using cst. Frequency is commonly measured in hertz, or cycles per second. They described the changes in frequency as phase shifts. Thus two sine waves differing in frequency by 200 hz get progressively out of phase with each other by 200 cycles every second. At first i wondered whether they were using some clever method of estimating the frequency shift by actually measuring phase shift which can be done with appropriate data acquisition tools and software, avoiding the need for a full fourier transform type acquisition. How can i plot the phase difference between fields components. From the pspice menu, choose a phase probe pspicemarkersadvanced phase of voltage and place it on the same node.

Using matlab, plot the frequency response magnitude vs.
