Let's talk about flexible absorbing materials used for radio frequency (RF) noise suppression and EMC shielding in electronic products such as cell phones, MP3 players, and rugged handheld devices.
The authors predict the internal electromagnetic field of a populated enclosure by using the diffusion model, and compare them with the fields obtained by the power balance method, a full-wave electromagnetic solver and measurements, to demonstrate its efficacy.
Understanding skin effect and surface currents saves us a lot of time and cost in the design of our product’s shielding and filtering, especially for tough EMC standards such as automotive, military or aerospace.
