Dipole Near Field Analysis – A Closed Form Calculation in Cartesian Coordinates

Abstract

This article deals with analytical calculation of the near-field of an electric dipole in Cartesian coordinate system in a closed form. Results of the analytical calculation are verified by numerical method.

Verifying the Performance Characteristics of the (micro) Robotic Devices

“…As an applicable approach, it seems using the new wireless principles to measure small displacements. One of it is described in the research works [19][20][21][22], where the electromagnetic principle is utilized. The principle of measurement is based on the detecting parameters changes in the electromagnetic field in which is placed the proposed mechanical device.…”

“…As a suitable position feedback ware indicated a new electromagnetic approach [20,22], where only parallel resonance circuit (capacitor and inductor) is situated on the compliant device. This minimizes additional space requirements.…”

Numerical Analysis of Isotropy Electromagnetic Sensor Measurement Error

“…This kind of voltage is coming from (2) basis and is also discussed in [3] and [5]. The reason of that is the interaction of EM field and the corresponding sensors.…”

“…All the methods are based on the interaction between the incident and radiated EM field of the studied objects (for example: two wires with lengths 2h). According to [3] or [4], the mutual impedance may be expressed as:…”

Sensor Interaction as a Source of the Electromagnetic Field Measurement Error

“…In the vicinity of sensor, the component E y is formed. Its magnitude is calculated in [4] The original incidence field is influenced by the presence of the field radiated by dipole. There are components formed which are not proper to the original field but to the influence of the sensor to its close neighborhood.…”
