Is there a permittivity and permeability table of the elements? Answered

I've found permittivity and permeability tables of the common metals, but none with all the elements. I know they measure them.

I don't think you're going to find such a complete table. First, not all elements will have had those properties measured; and second, they are strongly frequency and temperature dependent. The latter means that you'll either get a table for a fixed frequency and environment, or else you'll get a massive collection of phase-space plots from which you have to extract the data you want.

See, for example, reference 9 from the Wikipedia page Rick cited.

Is there a site with the tables and phase-space plots? I'm interested in rearranging the data to study the relationships.

This is the really fascinating area, for me. My Senior year of college, I would have said Ohm's Law was always accurate. Now I know that the current-voltage relationship isn't always linear, dependent on the material. We just do a really fantastic job of creating components, out of all the right materials, that behave linearly. It's fantastic if we want the same results we've been getting; but there is so much more.

I'm glad I started off in EE, but materials is where all the fun happens.

Okay, a Google search for "tables of permittivity" got me http://www.kayelaby.npl.co.uk/general_physics/2_6/2_6_5.html, which is relatively comprehensive. I'll leave subsequent searches to you.

One comment -- very few really useful electronic components are linear. Transistors are not, nor are diodes. An op-amp is decidedly nonlinear away from zero (in fact, you can use them to build perceptron-style neural nets). As you've gathered, the nonlinear properties of materials (and metamaterials) are an active and exciting area of current research in condensed matter physics.

Thank you. I'll continue the search. I really thought NIST would have a collection.

You're right. I probably could have phrased that more appropriately. I've had to take "electronic and photonic devices" like everyone else in school; so I know about their characteristics. Hysteresis is neat. But there are at least 3 guys who were trying to create a component with a negative current-voltage relationship in the 20's. They failed, from what I've read about so far, but they created some interesting stuff. And they always talk about using pure river water. :-) I'd love to know their setup for creating a vacuum inside a glass tube.

I don't know of an online site with that kind of data. You will probably need to either find published references, or do a Google Scholar search to figure out which research groups are active in this area.


Thank you. That table did have 2 more elements I haven't found. I'm looking for a table of the permeabilities and permittivities of all the elements. I've been scouring the internet for the last couple of days, but I'm no computer scientist.
