Resonant Transmission

Interaction of infrared electromagnetic (EM) waves in a layered structure with n- GaAs film is investigated theoretically. An oblique incidence of EM wave is considered, when the total internal reflection and resonant transmission occur. It is demonstrated that this structure modulates effectively the infrared EM wave. The modulation mechanism is due to the transfer of electrons from the upper valley to the higher ones in a strong bias electric field. An interaction of strong incident infrared EM pulses with this structure is also considered in the case of the absence of a bias electric field. Both the nonlinear switching of short pulses and the modulation instability of long strong pulses take place.

Radial Wave

Propagation of axially symmetric E-type and H-type modes of electromagnetic waves in a radially inhomogeneous plasma inside a wave guide is considered. For E-type modes conditions for the propagation of slow surface waves along the plasma–dielectric interface have been obtained. Approximate expressions for fields for wavelengths much smaller than the ratio of the gradient of the permittivity to the permittivity of the plasma are also given.It is also shown that if the dielectric constant ε(r) of the plasma vanishes along a particular surface r = r0, the electromagnetic fields for E-type modes behave singularly along this surface. In particular, if ε(r) has a simple zero at r0 ≠ 0, the radial and the longitudinal electric fields become singular as 1/ε(r0) and log ε(r0) respectively at r0. On the other hand, if ε(r) has a multiple zero at r0, the singularities of the above-mentioned fields will be as strong as a multiple pole at r0.Turning-point phenomena are also observed when the radial wave number [Formula: see text] vanishes along a surface. It is shown that the fields are oscillatory in the region [Formula: see text] and evanescent in the region [Formula: see text] for both E-type and H-type modes. The treatment of the singular behavior of the fields at ε(r) = 0, and of the turning-point phenomena at [Formula: see text], does not consider any boundary effect; therefore the results obtained here will be valid also for an inhomogeneous plasma column in free space.
