Angle Stability 3.4. Angle Stability As a consequence of the uncertainty the direction of in the electromagnetic wave, FSS, if sensitive On account of the uncertainty ofof the direction the electromagnetic wave, the the FSS, if sensitive for the incident will have a large deviation at its resonant frequency frequency when it to the incident angle, angle, will have a sizable deviation at its resonant when it resonates. resonates. In the event the deviation is also huge, the assure to maintain the proper spatial filtering If the deviation is too significant, the FSS cannotFSS can't assure to help keep the proper spatial filtering function inside the frequency band. Hence, the resonant frequency in the function inside the working working frequency band. Consequently, the resonant frequency of your designed FSS have to have very good angle under various polarized oblique oblique indesigned FSS have to have good angle stabilitystability below different polarizedincidences cidences to make sure that the FSS can reach stable operation frequency band. to make sure that the FSS can achieve steady operation to get a fixed for a fixed frequency band. Figure 10 shows the simulated reflection coefficients for various oblique angles of Figure 10 shows the simulated reflection coefficients for different oblique angles of incidence. Here, the angle imply deviation is AM9405 web defined to analyze the angle stability of your incidence. Here, the angle mean deviation is defined to analyze the angle stability in the proposed FSS and calculated as follows: proposed FSS and calculated as follows:f pnormal f pa1normal + f pnormal f pa2 + L + f pnormal f pan a a1 a typical f n fp + fp f p2 + + f p (5) p one hundred nf pnormal fp = one hundred (five) normal n fp a regular exactly where f p could be the resonant frequency at typical incidence; f p i will be the resonant frenormal is the resonant frequency at normal incidence; f ai is the resonant frequency where f p quency at ai angle; n is definitely the total number of oblique incident p angles.
