Polarization loss

`rho = polloss(fv_tr,fv_rcv)`

`rho = polloss(fv_tr,fv_rcv,pos_rcv)`

`rho = polloss(fv_tr,fv_rcv,pos_rcv,axes_rcv)`

`rho = polloss(fv_tr,fv_rcv,pos_rcv,axes_rcv,pos_tr)`

`rho = polloss(fv_tr,fv_rcv,pos_rcv,axes_rcv,pos_tr,axes_tr)`

returns
the loss, in decibels, because of mismatch between the polarization
of a transmitted field, `rho`

= polloss(`fv_tr`

,`fv_rcv`

)`fv_tr`

, and the polarization
of the receiving antenna, `fv_rcv`

. The field
vector lies in a plane orthogonal to the direction of propagation
from the transmitter to the receiver. The transmitted field is represented
as a 2-by-1 column vector `[Eh;Ev]`

. In this vector, `Eh`

and `Ev`

are
the field’s horizontal and vertical linear polarization components
with respect to the transmitter’s local coordinate system.
The receiving antenna’s polarization is specified by a 2-by-1
column vector, `fv_rcv`

. You can also specify this
polarization in the form of `[Eh;Ev]`

with respect
to the receiving antenna’s local coordinate system. In this
syntax, both local coordinate axes align with the global coordinate
system.

in addition, the orthonormal axes, `rho`

= polloss(`fv_tr`

,`fv_rcv`

,`pos_rcv`

,`axes_rcv`

)`axes_rcv`

.
These axes define the receiver's local coordinate system as a 3-by-3
matrix. The first column gives the *x*-axis of the
local system with respect to the global coordinate system. The second
and third columns give the *y* and *z* axes,
respectively. This syntax can use any of the input arguments in the
previous syntaxes.
