Article Snippet: As a numerical example or result of a double-helix FBAR array analysis, we will choose the median radius of the overall array as r = 20 cm (convenient laboratory size though usually somewhat greater than λ GW), Δ f = 2 N for an off-the-shelf FBAR and Δ t = 4×10-10 s (equivalent to about a ν EM = 2.5 GHz frequency or pulse of the jerk or energizing radiation frequency) so that λ EM =12 cm and λ GW = 6 cm (the frequency of the GW is twice that of the frequency of the energizing EM wave) and the power, P from the basic GW equation (its derivation can be found in, for example, Baker [10]. found by hyperlink at http://www.gravwave.com/docs/Astronomische%20Nachrichten%202006.pdf)) P=1.76×10-52 (2r Δ f/ Δ t)2 W. (1) For this equation the calculation of the combined ∆ f of all the pulsating MEMS or FBARs requires more calculation.
