problem on em plane waves the em plane wave can be represented by the real part of a complex electric field ve function e(r, t) = re (e, eik. f-ar assume the wave length is 500 nm and that the k vector is in the z direction. if electric field at the origin (at r = (x, y: ,0,0)) and at time t = 0 has field strength e-1.5 y = (0.1.5.0) volts/meter, then the functional form gives the field at other location points and times. g) at the same instant of time, compare the field at locations i with the field at r'= r + 1.23 wavelengths but where the position change r-r in a direction normal to r . give all components of the new electric field at f' h) again at constant time, if we consider the point that differs from the original location point with a displacement in a direction parallel to the k by n+½ wave lengths (with n-integer), then what can we say about the change in the electric field? i) lfk. : changes by 2π what is the change in the electric field?

step-by-step explanation:

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
