Before ever analyzing a chord and attempting to name it we should keep in mind that context has everything to do with how a chord is named (because chords may have harmonic functions, such as in the famed II-V-I progression). Consider this analogy: what does LIVE mean? You really can't answer the question (unless you want to give every possible answer) until you see/hear the word in a sentence.
She really knows how to live.
I went to a live concert last night.
In the first sentence we have a verb (a complimentary infinitive as a matter of fact); in the second an adjective.
So we must keep this in mind when wondering about what a given harmonic structure might be named.
So here's the chord in question, the open strings of the guitar...

There are 2 easy ways to analyze this chord completely out of context.
If it occurred in a tonal harmonic situation we could call it an E minor 7 add 11. We have all the notes of an E minor 7th: e, g, b, d as well as an a which is either the 4th or the 11th. Since 4s are usually sus let's just call this an add 11 -- that is we're viewing it as an extension of the triad. If there were an f# in the chord -- the 9th -- it would simply be an Eminor11. Another reason that this chord is e-ish is because there are 2 es. Nevertheless we don't have a context, and it isn't completely out of the question that the chord is not a G major (g, b, d) with an added 6 and 9 (e and a respectively) over an e.
But this chord is also even easier to analyze if we consider it as a quartal chord -- i.e. a chord built out of the interval of a perfect fourth (as opposed to thirds). In this case the lowest note (e, also the highest tone in the structure) is not the root. If we re-arrange the tones (and delete any repeats -- this is an abstraction for analysis) we can order them as: b, e, a, d, g -- five tones all a perfect 4th away from one another. When this chord shows up in the beginning of (say) Ginastera's Guitar Sonata it's probably best to assume that it's quartal and not triadic -- although other possibilities abound
Lastly (for our purposes) this could be part of a set of tones, for instance it could be a structure in a 12-tone piece (though with a duplication of a pitch class). In any situation like this it wouldn't get a name at all: it would simply be described numerically, such as (from low to high):
4 9 2 7 11 4. (This really depends upon what the reference pitch is: I've made C = 0 here, but it wouldn't have to be at all).
No matter what you call or how you describe it the chord sounds good...use it!
