IEEE Transactions on Electromagnetic Compatibility, 1978
A transmission line model of coupling to power lines has been developed that shows the effect of ground conductivity, angle of arrival, polarization, and power line geometry on the open-circuit voltage at the end of the line. With this information, and the characteristic impedance of the line, the current and voltage to any termination may be ...

EMP response of aircraft antennas
IEEE Transactions on Antennas and Propagation, 1978The responses of aircraft antennas to a broad-band electromagnetic wave such as the nuclear electromagnetic pulse (EMP) are analyzed. For convenience of analysis the antennas are divided into five classes: blades, loops, slots, bowls, and long wires. From each class a few specific antennas are selected as examples for detailed discussion.

ABSTRACT A procedure based on trasmission-line theory, is presented for the evaluation of the effects produced by an EMP wave on a multiconductor power line. The high-altitude nuclear EMP is considered as an incident wave towards the ground; the total field is the sum of the incident wave and the wave reflected from the ground surface. The transmission

Carcinoma of unknown primary (CUP) is defined as a metastatic carcinoma whose primary site cannot be determined, and the absence of a known primary tumor in CUP poses a significant challenge in treatment planning. The purpose of this study was to investigate the protein level of epithelial membrane proteins (EMP) 1, EMP 2, and EMP 3 in CUP and explore ...

Identification and analysis of ambient EMPs
Toxicology and Applied Pharmacology, 2018Mineral particles have long been observed in the ambient air and for >40 years, samples of these airborne particulate have been collected in attempt to identify and quantify the amount of asbestos particles in the air. For most of this time, regulated asbestos particles (in the shape of fibers) were the target for these analyses.

The character of transient electric fields induced in spherical homogeneous tissue models of man and animals by incident electromagnetic fields similar to that originating from lightning and EMP generators has been theoretically determined. The magnitude of the induced fields is found to be approximately proportional to the time rate of change of the ...

The purpose of this research paper is to investigate the business model of the retailer EMP. The in-depth literature review develops the relevance of merchandising for the rock and heavy metal scene and the relevance of EMP within that market. Literature about existing approaches of multi-channelling has been reviewed.

Although the nature of its threat is still debated, a number of narratives focus on an electromagnetic pulse (EMP) attack from a nuclear device detonated high in the atmosphere. The immediate effect is a near-total blackout and this fiction accordingly explores the possibilities of survival—individual or collective—in the civic breakdown which follows.

A bound on the energy coupled to a load by means of an antenna or aperture subjected to a step function electromagnetic pulse (EMP) is given by the polarizabilities of the antenna or aperture. Examples of coupling bounds for a slender electric dipole antenna, a circular aperture, and a narrow slot aperture with depth are given.

A complete analysis has been carried out of the twoconductor rhombic antenna as an EMP simulator. The distribution of current along the conductors and the electric field in the working space bounded by rhombic wires have been determined at low, middle, and high frequencies.
