All three <strong>of</strong> these conditions are easily achieved. (In particular, the third condition<br />
is automatic for degenerate modes in intersections with sufficient symmetry [the<br />
symmetry group <strong>of</strong> the square].) The resulting transmission pr<strong>of</strong>ile will be the typical<br />
spectrum <strong>of</strong> resonant tunneling--a Lorentzian (bell-shaped) curve centered on the<br />
resonance frequency. The width <strong>of</strong> the resonance is inversely proportional to the quality<br />
factor Q <strong>of</strong> the resonant mode (Q is proportional to the decay lifetime).
