Annotation
It is shown that as the thickness of а longitudinal semiconductor insert in а rectangular waveguide decreases, the effective lifetime of free carriers photoexcited bу light diminishes owing to the predominance of the surface recombination over the bulk one in thin plates. Ву contrast, in thick samples, the more protracted bulk recombination processes prevail. They provide а higher factor of microwave energy modulation but the time lag of the response is larger.
