Recall for a capacitor ɛ is the permittivity of the dielectric used, ε = € , & , & ,= relative permittivity and E. = permittivity of vacuum Assume "Doc" Brown's prototype flux capacitor used a super alumina oxide dielectric which achieved 1000X the permittivity of normal alumina oxide, or 40,000X the permittivity of vacuum, and can achieve 1 mm spacing between plates. Further assume "Doc" limits the cross sectional area of his flux capacitor to 1 square meter, in an attempt to fit in the Delorean (this is the overlap area of the plates; the entire capacitor is a little larger to account for the ends. Don't worry about this). Calculate the height required for the capacitor in #2.

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
