Title (EN) METHOD AND APPARATUS FOR ELECTROMAGNETIC EXPOSURE OF PLANAR OR OTHER MATERIALS
(FR) PROCEDE ET APPAREIL POUR L'EXPOSITION DE MATERIAUX PLANS OU AUTRES A L'ENERGIE ELECTROMAGNETIQUE
Abstract:
(EN) The present invention overcomes many of the problems associated with electromagnetic exposure of planar materials (40). A diagonal slot (36) compensates for the effects of signal attenuation along the propagation path. Adjustably variable path lengths allow peaks (17) and valleys (18) of the electromagnetic field (16) in one exposure segment (30) to compensate for peaks and valleys in another exposure segment. Dielectric slabs may be used to extend the peak field region between top and bottom conducting surfaces (12, 14) to allow for more uniform exposure of planar materials (40) that have a significant thickness (41). Specialized choke flanges prevent the escape of electromagnetic energy. One or more rollers between exposure segments (30) may be enclosed by an outer surface to prevent the escape of electromagnetic energy.
(FR) Cette invention permet de résoudre un grand nombre de problèmes associés à l'exposition électromagnétique des matériaux plans (40). Une fente diagonale (36) permet de compenser les effets de l'atténuation du signal le long du trajet de propagation. Des longueurs de trajets variables par réglage permettent aux crêtes (17) et aux creux (18) du champ électromagnétique (16) se trouvant dans un segment d'exposition (30) de compenser les crêtes et les creux se trouvant dans un autre segment d'exposition. Des plaques diélectriques peuvent servir à étendre la région du champ des crêtes entre les surfaces conductrices supérieure et inférieure (12, 14) pour permettre une exposition plus uniforme des matériaux plans (40) ayant une épaisseur importante (41). Des flasques d'arrêt spéciales empêchent l'énergie électromagnétique de s'échapper. Un ou plusieurs cylindres placés entre les segments d'exposition (30) peuvent être enfermés dans une surface extérieure pour empêcher l'énergie électromagnétique de s'échapper.
