A different sequence of electromagnetic pulses can be used to directly monitor Rabi oscillations between the two spin qubit basis states (Figure 7.7). As expected,... 

Classical pulse radar emits high power (Pr) short electromagnetic pulses using a directional transmitting antenna of gain Gt The power density at the target at distance R from the transmitter is equal to [44]... 

We note here that, for the sake of generality, both interactions are assumed as time dependent however, here, the time dependence in the interaction Vq p k E, n t) is assumed solely due to an electromagnetic pulse with a pulse form e t), in which case the V(k E, n) coupling matrix elements are time independent, and as such can be factorized out. 

We now must identify Hx(t). We shall assume that the perturbation is an electromagnetic pulse of the form...

In Section 2.1 we assumed that the electromagnetic pulse is infinitely long and that the amplitude of the field is constant in time [see Equation (2.13)]. In order to treat excitation with short laser pulses we must extend the theory to a more general electromagnetic field whose amplitude Eo(t) varies with time. The total Hamiltonian describing the evolution of the molecular system is given by... 

Since the early 1980 s it has been possible by means of electromagnetic pulses, to bring about the incorporation of drugs into biological cells, to open and shut pores... 

An electromagnetic pulse is sent into the ground. The reflected pulses are detected by an antenna held at the surface of the ground.

Electromagnetic pulses (EMPs) are also produced by nuclear weapons that are exploded at high altitudes, and are caused by the interaction of radiation from the explosion with electrons in the atmosphere and with the Earth s magnetic field. EMPs are essentially powerful radio waves that can destroy many electronic circuits.

An important application field for stainless steel fibers is the textile sector, in which 0., i to 6% of these fibers are incorporated to endow carpets, protective clothing etc. with an antistatic finish. A further application is protection against electromagnetic pulses, interference and charging. Tungsten fibers with a diameter of 12 pm are used for boron or SiC deposition and as light bulb filaments. Furthermore, metal fibers are used in the filtration of polymer melts and corrosive liquids, as well as for electrodes with high surface areas.
