Shear moduli of metal specimens using resonant column tests
The shear moduli of cylindrical metal specimens were determined by performing resonant column tests in a torsional mode of vibration. The tests were performed on four different metals, namely (i) aluminum, (ii) brass, (iii) copper, and (iv) mild steel ...

Dipole Resonant Modes of an Ionized Gas Column
It is shown by a quasi-static treatment there is not one but a multiplicity of plasma resonant modes which will emit dipole radiation in a cylindrical column of ionized gas with a radially symmetrical but non-uniform electron density.
