The Simulation of Electromagnetic Fields with Large Wavelengths

IOP Conference Series: Materials Science and Engineering, 2019
Abstract When the wavelength of an electromagnetic wave is much larger than the microscopic size of the material, the numerical solution of the model to study the effect of the material microstructure on the electromagnetic wave propagation usually fails to be obtained due to computational overload.

Direct measurement of the quantum state of the electromagnetic field in a superconducting transmission line

, 2006
We propose an experimental procedure to directly measure the state of an electromagnetic field inside a resonator, corresponding to a superconducting transmission line, coupled to a Cooper-pair box (CPB). The measurement protocol is based on the use of a
