Dede Djuhana, Ph.D

Welcome to

Firstly, My name is Dede Djuhana, I am a lecture at Department of Physics, Faculty of Mathematic and Natural Sciences, Universitas Indonesia. 

I have graduated from Doctor Program since 2010 from Department of Physics, Chungbuk National Univeristy, Cheongju, South Korea. 

My research focus on domain and domain wall investigation using micromagnetic simulation (OOMMF). Another, I also interest to study about plasmonic phenemona using optical modeling such as MNPBEM.
