For four decades, a quiet boundary in pure mathematics kept a powerful theorem locked inside the safe world of finite quantities. Now a new result known as Sebestyen’s theorem has pushed that boundary ...

Passive, lossy materials with positive index at real frequencies can be used to realize optical antimatter under complex frequency excitation. Our approach enables arbitrary complex \(\epsilon ,\,\mu\ ...

Plasma physics is the study of a state of matter comprising charged particles. Plasmas are usually created by heating a gas until the electrons become detached from their parent atom or molecule. This ...

Revising all formulas often and working through JEE Main questions from previous years will build the required speed and ...
