The merger of quantum mechanics with the special theory of relativity is commonly known as quantum field theory. According to this theory every particle of matter is just an excitation of a field that is everywhere in space. There is a different field for every different particle (this is not really true, but close enough). You might already be familiar with electromagnetism. In that theory (which has now been completely absorbed into quantum field theory) electric and magnetic forces are transmitted via photons. These photons are just excitations of the photon field. A photon has no mass, but all particles can be thought as as being excitations of fields. There is for example an electron field, but also a neutrino field and a muon field.
Circuit Theory: As the name suggests, circuit theory deals with electrical circuit. An engineer can predict the performance of complicated electrical networks with the help of circuit theory. But this theory has certain limitations like :It cannot be applied in free space.It is useful only at low frequencies.This theory is unsuccessful in explaining the radiation of electromagnetic waves into space in radio communications.It cannot be used to analyse or design a complete communication system. Example: Radio Communication System.Electromagnetic Field Theory. Although electromagnetic Field Theory (EMFT) is complex in comparison with circuit theory but EMFT is simplified by using appropriate mathematics. This theory deals with E and H vectors, whereas circuit theory deals with voltages and currents.This theory has following advantages in comparison to circuit theory:It is also applicable in free space.It is useful at all frequencies, particularly at high frequencies,The radiation effect can be considered.This theory can be used to analyse or design a complete communication system. Example: Wireless Communication, Radio Communication.Reference: This article is referred from my authored book "concepts of electromagnetic field theory".

Einstein is responsible for contributing numerous theories and understanding to the field of physics. Einstein published his Special Theory of Relativity, The General Theory of Relativity, and worked with Neil's Bohr to develop the basis for quantum mechanics.

If a sterile field becomes "contaminated" with a sterile solution, the field remains sterile.
