Abstract: We propose a directive antenna for borehole radar using a horizontally polarized wave in a vertical borehole. This antenna is an array of several horizontal loop antennas, arranged ...
Abstract: This paper presents an ultra-compact interdigital-loaded microstrip line-array lens (MALL) for passive beam steering and direction finding. The proposed structure implements a discrete ...
A BitSet (also called Bitmap or bit vector) is an ideal data structure to implement a set when values being stored are reasonably small integers. It can be orders of magnitude faster than a generic ...
