Dielectric constant distribution

As the particles become larger the width of the forward scattered lobe becomes narrower. The degree to which this occurs is important for interpretting multiply-scattered lidar signals as the forward-scattered radiation stays within the field-of-view of the receiver.

Electric field animation

This is an animation of the component of the electric field out of the plane of the page.

Average Poynting vector

The direction in which energy is travelling at any instant is proportional to the cross product of the electric and magnetic fields, known as the Poynting vector. The arrows show the direction of the Poynting vector averaged over the simulation, while the colours show its strength.
