These applications are based on the orthogonality property between the different topological charges of the received wave. In free space, this property can be conserved along the propagation path, but in a real environment, multipath effects can degrade the orthogonality between OAM modes, in particular due to the reflection on surfaces (ground, buildings ...) or objects, and the interference between waves.

Nous considerons un transpondeur lineaire comme cible et nous realisons une identification de cible grâce a la frequence de decalage induite par cette cible active. Les performances de localisation des radars FMCW bases sur la radio-identification dans la gamme (SHF) sont presentees et etudiees. Des simulations et des mesures viennent completer le papier.

The OAM mode ℓ = 1 is generated by combination of two TE21 modes inside a circular metallic waveguide. The resulting electrical field distribution and the radiation patterns evidence the properties of waves carrying OAM. The influences of the horn structure on the properties of the generated OAM waves are also studied.

The OAM mode ℓ = 1 is generated by using a spiral phase plate (SPP) inside a circular waveguide. We present here two methods to transform the classical guided modes to OAM wave. The resulting electrical field distribution and the radiation patterns evidence the properties of waves carrying OAM.

According to the invention, such a method includes, for at least one data symbol to be transmitted: a step of bijectively selecting (34) an orbital angular moment order, associating a separate orbital angular moment order with each separate value of a data symbol, and outputting a selected orbital angular moment order representative, by bijection, of the value of said at least one data symbol to be transmitted, a step of transmitting (35) said electromagnetic wave carrying an orbital angular moment whose corresponding orbital angular moment order corresponds to the said selected orbital angular moment order
