    摘要： A method of imaging biological tissue enables imaging structure in the biological tissue with an antenna tuned to emit radio energy through at least a covering layer of the biological tissue without significant attenuation of the radio energy. The method includes contacting skin covering tissue with a radio frequency emitting antenna, and adjusting at least one of a radiator and a feed in the antenna with reference to at least one measured electrical or physical property of the skin. The adjustment of the radiator and feed enable a combination of the antenna and skin to emit radio energy at a predetermined magnitude and frequency into a portion of the tissue covered by the skin.

    摘要： A chipless RFID tag system having a transmitter sending an input signal and a tag substrate. An ID generation circuit on the tag relies on microstrip transmission line patterns which are pre-designed to generate a unique code. The ID generating circuit may be designed based upon the transmission line properties, including signal delay, and/or reflection, and/or phase change. The tag may be formed on a flexible substrate having at least one microstrip and the microstrip having a first portion with a first impedance and a second portion with a second impedance different from the first impedance. The tag may further include a microstrip antenna for communication with the transmitter and a receiver system. The tag may also include sensors for detection of desired substances of interest. The system may further include a receiver detecting at least two reflections from an interface of first and second impedances and identifying relative time domain positions of the reflections to one another.
