A RFID (Radio Frequency Identification) tag with an electromagnetic band gap substrate is introduced to improve the performance of the RFID tag. The electromagnetic band gap substrate acts as a reflector to reflect electromagnetic wave emitted from RFID antenna. This reflected phase of electromagnet.....

Traditional methods for resistivity measurements of concrete have to use two plate electrodes at opposite sides of a prism specimen. The major drawback of such a method is that the electrodes can be easily detached from the specimen due to shrinkage of concrete. Thus the measurement of resistivity.....
