Abstract
To provide an electron tube capable of making an electromagnetic wave having a predetermined electric field oscillation direction appropriately incident on an electron emission part and appropriately multiplying electrons emitted from the electron emission part in response to the incidence of the electromagnetic wave having the predetermined electric field oscillation direction.SOLUTION: The electron tube 1 includes an electron emission part 3 including a metasurface 32 for emitting electrons in response to incidence of electromagnetic waves W having a predetermined electric field oscillation direction V, an electron multiplication part 4 for multiplying electrons emitted from the electron emission part 3, and a first mesh electrode 5 arranged between the electron emission part 3 and the electron multiplication part 4. The first mesh electrode 5 includes a plurality of wires 52 defining a plurality of openings arranged in a first direction D1 parallel to the electric field oscillation direction V. When viewed from the traveling direction T of the electromagnetic waves W, each of the plurality of openings has an elongated shape whose longitudinal direction is a second direction D2 intersecting the first direction D1 at an angle of 45 degrees or more.SELECTED DRAWING: Figure 5
