Abstract

See full text

An exposure device for exposing at least one object to an electromagnetic field, including a section of a waveguide or transmission line device including a guided electromagnetic wave, extending along a longitudinal axis, and including a hollow tubular electrical conductor inside which the electric field is established or plural electrical conductors between which the electric field is established. The device further includes a heterogeneous adaptation structure in mechanical contact with the electrical conductor or conductors, at least one extension element, and at least one housing for the object, contained in or positioned next to the extension element. The extension element is made from a material having a relative dielectric permittivity as close as possible to that of each object. The heterogeneous adaptation structure has a dimension, along the longitudinal axis, equal to a non-zero multiple of half-wavelengths of the electromagnetic wave to be propagated in the exposure device.
