The example simulates a pillar on a substrate, using one wavelength, whereas, I need a wvl range, so I changed the source’s wavelength to 0.5-1um. <\/p>\n
The height and radius dimensions are the same (as all other parameters from this example) – <\/p>\n
Height =1um, Radius = 0.144um. <\/p>\n
A few questions regarding the results – <\/span><\/p>\n (note – the Re(S21) is also larger than 1, not just the abs^2(S21))<\/p>\n Next, I would like to retrieve the phase data of the transmitted beam. <\/p>\n I see two options to achieve that – <\/p>\n the two methods give different results. <\/p>\n These graphs describe the scattering of my resonators (<\/span>not the original example). <\/p>\n This graph was taken from the GUI – S->visualize (angle(S21_Gn))<\/p>\n And this graph was taken after running the sweep and using the script. The “S.S21” matrix dimensions are – lambda, radius, height. In order to retrieve just the phase I’m using the lines – <\/p>\n lambda = linspace(3, 8, 1000);<\/p>\n folder_name = “phase_data_tr”;<\/p>\n <\/p>\n for(hei=1:nd)<\/p>\n {<\/p>\n for(r=1:nd)<\/p>\n {<\/p>\n phase1 = pinch(angle(S.S21_Gn),2,r);<\/p>\n phase2 = pinch(phase1,2,hei);<\/p>\n <\/p>\n A1 = [lambda, phase2];<\/p>\n filename = “phase_vs_wvl_r_” + num2str(radius(r,1))+ “_h_” + num2str(height(hei));<\/p>\n matlabsave(folder_name +’\\’+ filename, A1);<\/p>\n }<\/p>\n }<\/p>\n Then I plotted the phase in matlab (for the same radius and height as in the graph above) – <\/p>\n The graphs share the same behaviour for wvl =4-5.5um. However, around wvl =6.6um, the last graph shows a large dip, which has no sign in the first graph. <\/p>\n Which of the methods is the correct one? <\/p>\n <\/p>\n One last question – <\/p>\n How can I get the source’s wavelength (of the “grating_s_parameters” object) through the script? <\/p>\n I mean, I know the “start wavelength” and the “end wavelength” but are they evenly spaced?<\/p>\n Is it ok to use – <\/p>\n lambda = linspace(start wavelength, end wavelength, number of points); <\/p>\n in order to plot phase vs wvl? <\/p>\n thanks a lot in advance,<\/p>\n any help is much appreciated, <\/p>\n Shany<\/p>\n","protected":false},"template":"","class_list":["post-223140","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["260348","2592"],"_bbp_author_ip":["23.218.93.111"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1393"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["223140"],"_bbp_forum_id":["27833"],"_bbp_engagement":["2592","260348"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["223203"],"_bbp_last_active_id":["223203"],"_bbp_last_active_time":["2022-08-03 23:21:40"]},"test":"shanycobiu-ac-il"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/223140","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/223140\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=223140"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}\n
