Time-domain radiation and absorption by subwavelength sources

Radiation by elementary sources is a basic problem in wave physics. The authors show that the time-domain energy flux radiated from electromagnetic and acoustic sub-walength sources exhibits remarkable features. In particular, a subtle trade-off between source emission and absorption underlies the m...
