In 2006, Lambda Lambda Lambda fraternity was founded at UConn. Tri-Lamb does not discriminate based on race, gender, religion, class, or sexual orientation, unlike most fraternities. Starting a fraternity is not as difficult as you might think!
Tri-Lamb of course got its inspiration from the 1984 movie Revenge of the Nerds, a pop culture icon and treasure trove of 80s music. Watch the trailer for here.
But first a little history of Microwaves101... when we first started putting pages up, we used an older version of Dreamweaver. It used HTML version 3, which had a serious handicap. It didn't have Greek letters. So we created our own, and pasted them in as images. In February 2013 we finally updated this table, using html code, so we can add live links.
Here is a master source for html symbol codes.
|Letter name||Upper case||Use in microwave engineering||Lower case||Use in microwave engineering|
|Alpha||Α||α||attenuation constant of propagation constant, absorption factor,
temperature coefficient of resistance, thermal expansion coefficient,
transistor amplification factor
|Beta||Β||β||phase constant of propagation constant. transistor amplification factor|
|Gamma||Γ||reflection coefficient||γ||propagation constant
γ =(α+ jβ)
|Delta||Δ||difference port (monopulse network or rat race)||δ||skin depth, increment|
|Epsilon||Ε||ε||permittivity, base of natural logarithms (2.7128...)|
|Eta||Η||η||efficiency or impedance, η0 is the impedance of free space (376.7 ohms)|
|Theta||Θ||θ||phase angle, thermal resistance, azimuth in antenna measurement coordinate system|
|Kappa||Κ||κ||coupling coefficient, susceptibility|
|Mu||Μ||μ||prefix for "micro", or permeability, mobility|
|Rho||Ρ||ρ||magnitude of reflection coefficient, electric charge density, resistivity, radius|
|Sigma||Σ||sum port (monopulse or rat race)||σ||VSWR, conductivity, surface charge, radar cross section|
|Tau||Τ||τ||time constant (i.e. RxC)|
|Phi||Φ||φ||phase angle, roll in antenna measurement coordinate system|
|Omega||Ω||ohms||ω||angular frequency in radians/second|
Below is the original table we generated in Microsoft Word, which is merely an image, not "live" html.1 1 1 1 1 1 1 1 1 1 Rating 3.67 (3 Votes)
