Microwave
Lab Facilities
The main facilities consist of an Anechoic
Chamber,a Vector Network Analyzer, an Impedance Analyzer and a large
complement of coax, waveguide, cavity and free space setups. These
are used to provide testing services in the measurement of complex
permeability and dielectric constant of solid, granular, liquid and
other forms of material.
The broad sweep of the testing capability
is from about 1 MHz to 50 GHz. Typically, two-port measurements
in coax or waveguide are made to characterize materials that are
magnetic and dielectric. Such measurements are controlled using
Damaskos, Inc.'s "MU-EPSLN" software package for common analyzers
and IBM® compatible or Macintosh® PCs. Other configurations
in guided lines may offer advantages that are recognized, say for
dielectrics (mu = 1) or for liquids, and these too are supported
by "MU-EPSLN".
Many measurements are made in cavities
such as the Circular Cavity shown here. They are supported by the
appropriate
version of DI's "Cavity" instrument control and software package.
Such measurements, may be made with a vector or a scalar analyzer
of sufficient resolution. "Cavity" is used to measure both dielectric
and/or magnetic properties of materials that are of a form suitable
to the fixturing, often in a non-invasive manner with essentially
no sample preparation
