    Do Bees and Hornets Use Acoustic Resonance in Order to Monitor and Coordinate Comb Construction?

    We propose that social hornets and bees, who construct large arrays (known as combs) of cells for hatching and brooding their offspring, exploit ultrasonic acoustic resonances in those cells in order to implem...

    Nonlinear Behavior and Optical Bistability in Composite Media

    The nonlinear response of a composite medium to an external electric field can be greatly enhanced if the system is near a strong isolated quasistatic resonance. This situation, achievable in metal-dielectric ...

    Effective Medium Approximation for Nonlinear Conductivity of a Composite Medium

    Bruggeman’s Self-Consistent Effective Medium Approximation for the linear conductivity of a composite medium is reformulated in a manner such that the averaging procedure that must be used becomes unambiguous....
