Farfield analysis
WebThis analysis can take about a minute because there are a large number of far field projections involved and we record data at several different wavelengths - a new farfield projection is required for each wavelength. The script will create two figures. The first figure shows the reflected power measured using the power direction group, which ... WebThis analysis group calculates the S parameters (amplitude and phase) of a metamaterial, based on grating projections of the near-field data collected by DFT monitors for transmission and reflection. The analysis group isolates a particular output grating order, which can be selected by the user (see the analysis properties description below).

WebJan 17, 2008 · For better understanding, you can include the structure along with the far-field (just right click on the 3-D pattern, plot properties -> show structure). you can also see the polar plot by cutting the plane along theta or phi axis. if you need some background on field plot, read one antenna book like Balanis. Directivity and efficiency: WebThe farfield projection along the propagation axis (z) shows that the focal distance of the metalens is about 79.4 um. The FWHM (Full Width Half Maximum) of the beam at the focal plane is about 2.4 um. The calculated focal distance is …
