SHG spectrum

Post by sdwang » Fri Aug 30, 2024 4:57 am

Dear all,
How could I get the epsilon(omega/2) spectrum (as attached) for comparison with SHG results?
Thanks

Jingqi

Dear Jingqi

just calculate the normal epsilon and then plot it with w/2, for example in gnuplot

plot 'epsilon.dat' u 1:2 t 'epsilon(w)'
plot 'epsilon.dat' u ($1/2):2 t 'epsilon(w/2)

best
