When light is incident to an antenna layer AA6 of a photocathode AA1, light of a specific wavelength included in the incident light couples with surface plasmons in the antenna layer AA6 whereupon near-field light is outputted from a through hole AA14. The apparatus comprises a transmitter unit including a transmitter ; a receiver unit including a receiver ; and an operational interface. tampons, sanitary napkins, panty liners and the like, and the process for their preparation in which a hydrophobic andor cationactive layer is attached to a conventional absorbent layer, for the binding of microorganisms, specifically for treating or alleviating or prophylactically preventing vaginal fungal infections. The use of pneumatics further provides an extremely swift blade motion which reduces the likelihood of bruising to the vegetable as well as inaccurate portioning. The light-emitting arrangement according to the invention provides greatly improved heat removal from the LED while using a low-cost glass-epoxy material for the PCB.
