Goos-Hanchen and Imbert-Fedorov shifts in temporally dispersive attenuative materials

The Goos-Hanchen (GH) and Imbert-Fedorov (IF) shifts for the reflection of the beam impinging upon a plane interface separating two temporally dispersive attenuative materials (TDAMs) are studied theoretically and numerically. It is revealed that at the critical angle c, the GH shift arrives at a positive maximal value, while the IF shift reaches zero. Meanwhile, at the Brewster angle B, a peak GH shift, which can be a negative or positive value, appears only at the TM(p)-polarization state. Apart from (c) and (B), (m), a special and interesting incident angle related to n1 '' n2 ''
