1. A system comprising:
a power storage component:
a power converter;
a signal reflector;
an antenna unit configured to receive a radio frequency signal;
a switch component electrically coupled to the antenna unit, wherein the switch component is associated with a plurality of signal processing states that comprise at least a collection state and a reflection state and is configured to:
(i) route the radio frequency signal to the power converter in the collection state, and
(ii) route the radio frequency signal to the signal reflector in the reflection state; and
a controller configured to selectively transition the switch component between the collection state and the reflection state based at least in part on a power capacity of the power storage component, wherein:
(i) the plurality of signal processing states comprises a first reflection state and a second reflection state,
(ii) the signal reflector comprises a first delay line circuit corresponding to the first reflection state, the first delay line circuit configured to generate a first reflected electrical signal for retransmitting the radio frequency signal in a first direction, and
(iii) the signal reflector comprises a second delay line circuit corresponding to the second reflection state, the second delay line circuit configured to generate a second reflected electrical signal for retransmitting the radio frequency signal in a second direction.
