Boundary radiation prevention structure and electronic cabinet and electronic working platform using the boundary radiation prevention structure

An electronic cabinet with a boundary radiation prevention structure for placing at least one object attached with an electronic tag, wherein the electronic cabinet includes a plurality of compartments, each compartment comprises:

• at least one antenna for coupling to the electronic tag;
• a plurality of metal portions, each metal portion is located between two compartments and has two incident planes corresponding to the compartments respectively for blocking the incident electromagnetic wave across to another compartment, wherein the incident electromagnetic wave induces an induced current on the incident plane;
• and
• a plurality of guide portions, which are located between two incident planes and each guide portion has a curved surface electrically connected to the metal portion for the induced current to pass through, wherein the curved surface is covered by an absorption layer for absorbing of the incident electromagnetic wave and a boundary radiation generated from the induced current radiation.
