Question

In resonators with nanoscale I-beams, which factor does not affect the mechanical frequencies of I-beams?

a.

Size

b.

Density

c.

Stiffness

d.

Distance between beam and bottom of the cavity

Posted under Cognitive Radio

Answer: (b).Density Explanation:In resonators with nanoscale I-beams suspended over the cavity, the mechanical frequencies of I-beam are determined by size and stiffness of I-beam, and the distance between the beam and bottom of the cavity.
