Axial Static Magnetic Field

The expressions for the radiated fields of an arbitrary slot on a conducting cylinder coated with a cold plasma sheath with an axial static magnetic field are obtained. It is well known from the plane-wave analysis that the presence of a static magnetic field has a considerable effect on the transmission characteristics of the signal through the plasma sheath. The principal concern of this paper is to consider the effects of a static magnetic field on the radiation pattern of a plasma-coated slot antenna. Extensive numerical computations are carried out for the special case of an infinite axial slot. It is found that, if the plasma frequency is moderate, a small axial static magnetic field could change significantly the radiation patterns of the slotted antenna. Furthermore, owing to the anisotropy of the plasma medium, the radiation patterns are asymmetric.

Transient Voltage

In a recent paper, Lee (1981) developed an asymptotic formula for the coincident loop transient electromagnetic (TEM) response of a polarizable half‐space having a Cole‐Cole impedance. By using parameters corresponding to three different mineral deposits, Lee showed that negative transients would be obtained for delay times of 0.4 to 1.1 msec. The method developed by Knight and Raiche (1982) to calculate the transient response of layered earths was used to check these results for three reasons.

Sodium fluoride solution was injected i.p. to three groups of rats at a dose equivalent to 0.1 LD50 three times a week up to 18 injections. Two out of these groups and two out of three groups were sham-injected with normal saline and were exposed to the whole body impact of a 25 mT static magnetic field (SMF) for 2 or 4 hr a day, 5 times a week. Following the exposure, various functional and biochemical indices were evaluated along with histological examination and morphometric measurements of the femur in the differently exposed and control rats. The mathematical analysis of the combined effects of the SMF and fluoride based on the a response surface model demonstrated that, in full correspondence with what we had previously found for the combined toxicity of different chemicals, the combined adverse action of a chemical plus a physical agent was characterized by a tipological diversity depending not only on particular effects these types were assessed for but on the dose and effect levels as well. From this point of view, the indices for which at least one statistically significant effect was observed could be classified as identifying (I) mainly single-factor action; (II) additive unidirectional action; (III) synergism (superadditive unidirectional action); (IV) antagonism, including both subadditive unidirectional action and all variants of contradirectional action.
