WebFields are computed in the Fresnel and Fraunhofer regions. A dual-reflector system (Cassegrain)is also simulated for the transmitting case, and fields are computed in the Fraunhofer region. Appended results include derivations which show that the vector Kirchhoff-Kottler formulation has an equivalent form requiring only inci-

WebElectromagnetic attack. In cryptography, electromagnetic attacks are side-channel attacks performed by measuring the electromagnetic radiation emitted from a device and performing signal analysis on it. These attacks are a more specific type of what is sometimes referred to as Van Eck phreaking, with the intention to capture encryption keys. christophe jeanne cardiologue

WebGenerally, the varying fields are bifurcated into near-field and far-field regions. The near-field and far-field regions correspond to the electromagnetic fields nearer and farther from the antenna, respectively. The most commonly-used parameter to define near-field vs. far-field regions is signal wavelength.
