How a metal plate become polarised
WebAn electric dipole in an external electric field is subjected to a torque τ = pE sin θ, where θ is the angle between p and E. The torque tends to align the dipole moment p in the … WebYou can easily show that these microwaves are polarised when they are emitted. This can be done just by putting a receiver in front of the transmitter, and then rotating either around the direction between them. When they are 'crossed' (at right angles) the signal reception drops to zero. A polarising filter can be made of a grille of metal wires.

A wave plate in which the phase … WebA neutral conductor (or dielectric) experiences a torque, but no net force, when placed in a uniform electric field. It does experience a net force in a non-uniform field. What it shows: When an electrically neutral object is suspended in a uniform electric field, it becomes polarized. The electric force on the separated charges produces a torque about the …
WebFig. 6.1.1: A plate 6.1.2 Plate Theory Plates subjected only to in-plane loading can be solved using two-dimensional plane stress theory1 (see Book I, §3.5). On the other hand, plate theory is concerned mainly with lateral loading. One of the differences between plane stress and plate theory is that in the plate theory the Webwhich is linearly polarized in the vˆ direction. The magnetic field will be polarized in direction 90 behind the electric field. Remember, we always implicitly want to have the real part of these fields. So, for linearly polarized light in the x direction, the fields are actually Re E~ =(E0cos(kz −ωt),0,0), Re B~ = 0, E0 c cos(kz−ωt ...

WebAn electric dipole in an external electric field is subjected to a torque τ = pE sin θ, where θ is the angle between p and E. The torque tends to align the dipole moment p in the direction of E. The potential energy of the dipole is given by Ue = − pE cos θ, or in vector notation Ue = − p · E.
