Scale-down models for targets are used for radar cross-section measurements of huge-size
objects. Is there any upper limit to the scaling factor on downscale modeling as a 100 m length of
target becomes 2 m when downscaled by a factor of 50? Will it satisfy the results?
Solution
I guess there can be some limitations. If you use a model that is 50 times smaller than the target,
the wavelength for the model must be 50 times smaller than the wavelength for the target, so the
frequency must be 50 times greater. The imaginary part of the electric permittivity is 4??? (in
CGS), where ? is the frequency, ? is the conductivity. So, for example, if your target is made of
copper, your model\'s material must have conductivity 50 times greater than that of copper, and
there is no such material, as far as I know (I don\'t think using a supercoductive material would
help). Similar (but probably less severe) problems can arise with the real part of electric
permittivity, as it tends to be smaller for higher frequency..

1. Scandura (1999) employs LMX Theory in her exploration of the concept, “organizational
justice.” What is meant by organizational justice? How and why is this an important part of the
leader-follower relationship?
Solution
Organisational Justice:
Justice is an important concern for organisations as well as employees operating in both formal
and informal environment. There are four types of justice – Procedural, informational,
distributive and interpersonal.
Leader Member theory or LMX theory suggests a unique type of relationships developed with
each subordinate, rather than same style dealing with members. Organisational justice gives the
subordinate confidence to deal with different situations. The justice is deeply influenced by
leader and should be taken in confidence of member.
