Hi !
I use optiFDTD to simulate this structure gold lines/VO2 film/Sapphire substrate
When I put refractive index of VO2 at 25 C is: gold/ Vo2_cold (n=3.00433 and k=-0.3851)/sapphire
The program runs well, but
When I put refractive index of VO2 at 100C is: gold/Vo2_hot (n=1.63834 and k= -1.59661)/sapphire
After running 2D simulation with mesh 0.001 for X and Z, I open observationline1 and the error “Encountered an improper argument” appears
Could you please tell me where my mistake is and how to fix it ?
I attached my programs in this topic
Thank you
