Question:

Scattering From Dielectrics?

Hi, I have a quick question concerning electromagnetic wave scattering when it is incident with a dielectric material.If the material has a dielectric constant of, say, 3, there should be less scattering from this material, when compared to something that has a dielectric constant of say, 6, correct?Also, what is the dielectric constant of something like copper metal sheets? It is a conductor, but what is the dielectric constant of that, if that is even able to be determined?Thank you.

Answer:

Go for the cheap one, thats what I did and it works fine. I did it for the mileage also. I gained 2.6 mpg on the highway, and 3.1 in the city.
What you have to keep in mind is what do you expect to get from putting this on your car? are you looking for performance or mileage or just a little playing around? also you need to know what other parts you need to replace to reach your goal. there is a difference but it depends on what your after. No matter how much money you have you can spend more.
Dielectric response in polar dielectrics with respect to external temperature, frequency, electric field, and pressure is an important issue in dielectric physics. The dielectric constant k is the relative permittivity of a dielectric material. It is an important parameter in characterizing capacitors. It is unfortunate that the same symbol k is often used for Coulomb's constant, so one must be careful of this possible confusion.
