hi, nowadays I try to get involved electromagnetic waves equations, and I came across that $$ \nabla $$ is treated like $$ ik $$ and $$ \frac {\partial } {\partial t} $$ is treated like $$ -iw $$ And if you look at the part painted with orange in my attachment, afterwards you can see that $$ \nabla $$ and $$ \frac {\partial } {\partial t} $$ is equated to the $$ ik $$ and $$ -iw $$ respectively. It is so weird because those operators are equated to a number. How is it possible? What is the logic of this situation ? Is there a proof of that situation?
I am looking forward to your valuable responses. Thanks in advance...
