One radar that has gained popularity due to its ability to scan a large field of view is the phased array radar(PAR). [One] traditional PAR [is] known as a passive electronically scanned array(PESA). In the PESA, a single transmitter generates a high-powered signal that is transmitted through individual antenna elements. Each transmit element has an associated computer-controlled phase shifter... that creates a directional beam by adding a phase shift to the signal from each element. The narrow beam is sequentially steered through the field of view by changing the phase at each element.  4, record 1, English, - passive%20electronically%20scanned%20array

Circuit of electric field measurements of thunderclouds.... The electric field mill is a device based on electrostatic induction. It consists of one or two electrodes which either rotate in an electrostatic field or become periodically exposed to a field by rotating vanes. Fig. 46 illustrates a cylindrical field mill which consists of two cylinder halves that are electrically insulated from each other. An electric motor rotates the two halves in the electric field to be measured so that they become alternately exposed to both the positive and negative direction of the field. The result is that an alternating(ac) signal is generated across the two halves which can be easily amplified.... Although not commonly used, the cylindrical field mill has the advantage that when mounted in a fixed position it can also indicate the direction of the field. This is accomplished by measuring the phase shift of the ac signal relative to the orientation of electric fields need to be measured.  2, record 8, English, - cylindrical%20field%20mill

The device normally used to measure atmospheric electric fields is a type of sensor called an electric field mill. It can be used on the ground to gain information about the field aloft, or it can be flown on an airplane or balloon. Thirty-one ground-based field mills at Cape Canaveral Air Force Station and the Kennedy Space Center are used to measure the electric field just above the surface of Earth, in the lowest meter of the atmosphere, and determine if it meets the safety levels specified in the Lightning Launch Commit Criteria. The small, cylindrical field mill is mounted upside down.  3, record 8, English, - cylindrical%20field%20mill

... the electrorheological effect lies in a phenomenon termed electrical polarizability. In an electric field-between, say, a pair of charged metal plates-the positively charged protons inside a particle will be attracted toward one electrode while the negatively charged electrons will be attracted toward the opposite electrode. The result is that the positive and negative charges shift somewhat inside the particle, each in an opposite direction. A particle in an electric field thus becomes an electric dipole, whose positive and negative poles are analogous to a magnet's north and south poles. The strength of this effect varies according to the electrical polarizability of the substance. If the polarizability is large, then large amounts of electric charge shift over large distances toward the particles’ opposite poles. If the polarizability is small, then the particles hardly respond at all to an applied electric field.  1, record 9, English, - electrorheological%20effect

Il en résulte un déplacement, dans des directions opposées, des charges positives et négatives. Une particule dans un champ électrique devient ainsi un dipôle électrique dont les pôles positif et négatif sont analogues aux pôles Nord et Sud d'un aimant. L'intensité de cet effet varie selon la polarisabilité électrique de la substance.
