The attachment shows the geometry simulated.&nbsp;Dielectric constant of the waveguide is 6.15, and the dimensions of the dielectric waveguide is 0.127 x 1.87 x 10 mm3. When I change the port size, the magnitude of S21 also changes. When the port size increases, S21 also increases and vice versa. I could not find the guideline to model the proper waveport size as to get a convincing result.<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/30537f95-cb50-4ac8-a4a6-a96300b2557a\/870661bd-2598-43a5-963c-a96500802b4f_simulated-geometry.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p>*Pink rectangular are the waveports, the purple object is the dielectric waveguide*<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/30537f95-cb50-4ac8-a4a6-a96300b2557a\/f5c50308-2198-4351-97df-a96500804282_s21-variation.jpg?width=690&amp;upscale=false\" alt=\"\">&nbsp;<\/p>\n<p><\/p>\n<p>Does anyone have experiences in modeling dielectric waveguide in HFSS?
