Claim:
1. An apparatus comprising: a waveform detector operable to detect a waveform; a membrane encircling the waveform detector, the membrane having a first portion that is at least partially transparent to the waveform and having a second portion that is at least partially reflective of the waveform; a support member having a first end for mounting the waveform detector and the membrane at a location and having a second end opposite the first end and inside the membrane coupled to the waveform detector, wherein the support member is configured to support, at the second end, the waveform detector within the membrane; one or more movable components coupled to the support member and to the waveform detector, wherein the one or more movable components are configured to move the waveform detector relative to the support member; a controller external to the membrane, the controller configured to control movement of the waveform detector, via the one or more movable components, to align the waveform detector with a focal point of the waveform within a focal area of the membrane, and a transmitter coupled to a first side of the waveform detector such that the transmitter is aligned with a remote communication system sending the waveform when a second side of the waveform detector is aligned with the focal point.
