Standing wave-generating planar wave illumination units generate two light-wave planar waves using light from a light source assembly and irradiate a sample surface with a standing wave produced by interference of the planar waves on the sample surface. The power amplification modules are oriented in an electromagnetic energy field so that input electromagnetic energy is coupled to the input of the power amplifier by the input side stepped impedance transition, amplified by the amplifier, and emitted from the module by the output side stepped impedance transition. Also, the switch is connected to the contact module. A placement device used in the process and a portable object including an electronic assembly placed according to the process are also objects of the present invention. Each housing has a channel that can be aligned to communicate with the inside of the flow orienting duct of the central axle, responsible for orienting the produced mixture to a top reservoir with a foam-making nozzle. Security on the mobile device based may be provided by biometric identification and calculation of variance from regular movement patterns.
