ABSTRACT:
An electron tunneling device includes a first non-insulating strip and a second non-insulating strip spaced apart from one another such that first and second end portions, respectively, of the first and second non-insulating strips cooperate to form an antenna having an antenna impedance. The first and second non-insulating strips include a transition region that extends from the antenna to a tunneling region in which the first and second non-insulating strips are in a confronting relationship. An arrangement cooperates with a portion of each of the first and second non-insulating strips in the tunneling region to form an electron tunneling structure exhibiting a tunneling region impedance. The transition region is configured to match the antenna impedance to the tunneling region impedance. The transition region can provide for changing an electromagnetic field orientation between the antenna and the tunneling region.
