In that case I have a related question. I&#8217;m currently doing simulation times of 30ps, stabilized boundary 30PML layers. However, when I use a narrow wavelength spacing (e.g less than 10nm), or I add a custom (n,k) import, I get oscillations in my dipolepower and transmission. My thought is that since the dipolepower monitor is placed at the center, the oscillations could be caused by reflections, or PML relfections. Additionally, I also see these oscillations in the transmission outside the photonic crystal. What could be causing those oscillations in power?&lt;\/p&gt;&lt;p&gt;Example below is for custom (n,k) import&lt;\/p&gt;&lt;p&gt;Dipolepower:&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/24-01-2024-1706124974-mceclip1.png\" \/>&lt;\/p&gt;&lt;p&gt;Transmission:&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/01\/24-01-2024-1706124945-mceclip0.png\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-346431","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hi Amrita,Thank you for the reply.
