Dear friends, I'm trying to write a code to simulate material with PT symmetry. But I'm not sure how to include gain and loss in the dielectric constant.
For example, can we use the material library to modulate material gain and loss? Or is it necessary to write the epsilon function by hand? Thank you very much to all. -- Cícero Julião da Silva Junior ____________________________________ Instituto Federal de Alagoas - IFAL Campus Murici http://www.ifal.edu.br/
