摘要:

The electric and magnetic fields for a hollow conducting sphere located in a slowly varying uniform electric field background are computed to first‐order in a power series expansion in the field frequency. These results are used to define an equivalent RC circuit and to test the circuit approach which is often used in electromagnetic compatibility (EMC). The case of an infinite cylindrical conducting tube under the influence of the same external field is also analyzed.
