A series tee splitter comprises a primary electromagnetic transmission line and a secondary electromagnetic transmission line that is placed in a series path with the primary electromagnetic transmission line, wherein a load is attached to the end of the secondary electromagnetic transmission line and a network analyzer is connected to opposite ends of the primary electromagnetic transmission line to measure a load impedance. This configuration increases the high impedance measurement limit of the network analyzer normally seen for reflection measurements. The series tee splitter can be electrically small to provide broadband impedance information.

The focus of the teachings is on using Compact ferrite antenna to detect the motion of metal objects using a very low frequency (VLF) square wave, propagated between a pair of compact ferrite-particle dielectric-core RWA antennas in free space. The two salient features in the signal are observed; both of which are characteristic of Brillouin-precursor propagation: (1) a temporal Bessel-like waveform; and (2) an algebraic, rather than exponential, attenuation with distance over three meters. The key element teaching shows pair of source and detector antenna enables the detection of metals (weapon gun, knife) on a person or package between the ferrite-particle dielectric-core antennas-source (S) and detector (D) pairs or arrays of S-D tractor. The detection consisted of a change in the amplitude of the Bessel-like waveform of the received signal for security system to detect weapons.

Various examples are provided related to anisotropic constitutive parameters (ACPs) that can be used to launch Zenneck surface waves. In one example, among others, an ACP system includes an array of ACP elements distributed above a medium such as, e.g., a terrestrial medium. The array of ACP elements can include one or more horizontal layers of radial resistive artificial anisotropic dielectric (RRAAD) elements positioned in one or more orientations above the terrestrial medium. The ACP system can include vertical lossless artificial anisotropic dielectric (VLAAD) elements distributed above the terrestrial medium in a third orientation perpendicular to the horizontal layer or layers. The ACP system can also include horizontal artificial anisotropic magnetic permeability (HAAMP) elements distributed above the terrestrial medium. The array of ACP elements can be distributed about a launching structure, which can be excited with an electromagnetic field to facilitate the launch of a Zenneck surface wave.
