In summary, the conversation is about someone seeking help with using the 3D electromagnetics application mode in COMSOL to model the wave propagation through different materials. They are specifically looking for information on boundary conditions and fixing the frequency of the wave. Another person, David, provides helpful data and suggests checking out Yang's paper for more detailed model setting. The original person expresses gratitude for the information and hopes David will share their finished work for others to learn from.

COMSOL help- very URGENT

Hi there...
Can anyone help me to model the wave propogation through a block of material using the 3D electromagnetics application mode in comsol? I want to simulate the attunation in the intensity of wave when it travels through different materials like Si, Ni, etc...I would like to know about the boundry conditions we use and how we fix the frequency of the wave...
someone please do help me soon...
thankyou...
