✦ Synopsis

Comparing with measured data, K was found to have a value Ž . of 6, giving the modeled result shown in Figure a .

NORMALIZED FREQUENCY

Ž .

Consider Figure b . The resonant frequency may be simply modeled by a first-order approximation by reducing surface currents to three simple paths and taking an average of their total length: Ž .
