The unintentionally radiated power density from electrically large electronic equipment shows a strong directional dependence. The polarization of the emitted field is also a priori unknown. Time and economy makes it prohibitive to measure all orient

The susceptibility of electronic equipment against electromagnetic irradiation depends on irradiation direction and polarisation. We show how this dependency can be taken into account when performing a radiated susceptibility test in the reverberatio

The polarization coupling between a random emitter and a measurement antenna is uniformly distributed between 0 and 1, independent of the receiving polarization of measurement antenna in use. The polarization efficiency when performing a radiated sus

The electric field in nested reverberation chambers is Rayleigh distributed. Positioning an antenna in each of two nested reverberation chambers, the transmission amplitude coefficient between the two antennas is double Rayleigh distributed.

During chemo- and radiation therapy, the balance between epithelial cell proliferation, differentiation, and cell death at the villus tip is disrupted by premature death of dividing epithelial cells. This will subsequently lead to the onset of mucosa

We have developed and implemented a fast code to calculate the worst case electromagnetic threat inside shielded electromagnetically large rooms. The code is numerical but based on experiments and analysis, and typical outputs of the code are the max

Porous insulators offer new opportunities for the controlled guest–host synthesis of nanowires for future integrated circuits characterized by low propagation delay, crosstalk and power consumption. We propose a method to estimate the effect of the

The reverberation chamber is a good tool to perform high level radiated susceptibility testing. The accuracy and repeatability is good, and the testing time is short. However, the susceptibility of electronic equipment depends on from which direction

We present analytic expressions to quickly calculate the maximum electric field and power levels inside an electromagnetic shielded cavity. Typical maximum values are 9–11 dB larger than the corresponding average values. The method is applicable to
