“…It was shown in [3] that for obliquely incident laser radiation and when the condition T 0 /T p ∞ is ful filled, the maximum energy of electrons leaving the discharge gap depends on the angle of incidence θ of 2m/eϕ 0 laser radiation: ε = eϕ 0 cos 2 θ. This leads to a decrease in the wave amplitude proportional to cos 2 θ and a decrease in the electromagnetic energy flux density over the anode in proportion to cos 4 θ.…”

An approximate analytic solution of Maxwell's equations is obtained inside a photodiode. Analy sis of this solution shows that the earlier discovered significant decrease in the radiation field characteristics over an anode is caused by a considerable increase in the amplitude of a wave generated inside the photodiode, which for angles of incidence θ π/2 achieves a value comparable to the initial electric field strength applied to the photodiode. In this case, the electromagnetic energy flux density inside the photodiode exceeds tens times or more the electromagnetic energy flux density over the anode. The results of numerical calcula tions confirm the analytic results.

“…Our bound on the radiated energy also includes the size scale of the diode as a parameter. It is not possible to derive a single bound for more complete models and calculations of charges and currents in vacuum diodes 12,13 (these authors did not calculate the emitted radiation), because they must be described by several independent parameters. A quantitative bound would require optimization over a several-dimensional parameter space; its origin would not be apparent and its numerical value would depend on detailed geometric assumptions.…”

Vircators (Virtual Cathode Oscillators) are sources of short-pulsed, high power, microwave (GHz) radiation. An essentially dimensional argument relates their radiated power, pulse energy and oscillation frequency to their driving voltage and fundamental physical constants. For a diode of width and gap 10 cm and for voltages of a few hundred keV the peak radiated power cannot exceed ${\cal O} (\text{30 GW})$ and the broad-band single cycle radiated energy cannot exceed ${\cal O}(\text{3 J})$. If electrons can be accelerated to relativistic energies higher powers and radiated energies may be possible.Comment: 6 p
