I set the planewave source (940nm) to y polarization and want to record the movie of the E field being reflected back. I set two movie monitors, one is x-z direction (2D Y-normal) and another is y-z direction (2D X-normal).&lt;\/span&gt;&lt;\/p&gt;&lt;p&gt;&lt;span lang=&#8221;EN-US&#8221; style=&#8221;font-size: 11.0pt; mso-bidi-font-size: 12.0pt; line-height: 115%; font-family: &#8216;Times New Roman&#8217;,serif; mso-fareast-font-family: \u7b49\u7ebf; mso-fareast-theme-font: minor-fareast; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;&#8221;&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/12\/12-12-2024-1733982699-mceclip0.png\" width=\"668\" height=\"476\" \/>&lt;\/span&gt;&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;&lt;span lang=&#8221;EN-US&#8221; style=&#8221;font-family: &#8216;Times New Roman&#8217;,serif;&#8221;&gt;But in the movies (for both the two monitors), the E field transmits through the structure and there is no light being reflected back. The following are the third second and sixth second of the movie.
